Had the same problem. Adding -fno-stack-protector to CFLAGS solved it for me.
Why did this just start happening?
(In reply to comment #6) > Why did this just start happening? because 5.8.7 has been in our tree for maybe a good 24 hours now, tops (~arch'd)
I think what solar meant was, what's changed between perl 5.8.6 which compiled fine for all us hardened guys, and 5.8.7 which suddenly doesn't like us anymore... The most useful reply I can think of is that it's related to the following from the perldelta page: "The internal pointer mapping hash used during ithreads cloning now uses an arena for memory allocation. In tests this reduced ithreads cloning time by about 10%." That seems to be the only noticable change.
FWIW, the solution described in #5 worked for me.
*** Bug 97813 has been marked as a duplicate of this bug. ***
Also happends for me, not sure if disabling the hardended part is a usable solution for all, since it might lead to some security problems, right?

Created attachment 62570 [details, diff] perl-5.8.7-cflags-regexp.patch Patch that disables ssp on the two regexp files in perl. Allows perl to build and run while keeping ssp active everywhere else we can. I think the segfault happens with any ssp code when a function recursively calls itself a bunch of times. Seen this is other regexp code before with ssp.
Ok, this patch work for me But I don't know if it's the better solution or if it's the miniperl algorithm that should be corrected... Thanks
the root of the problem should be fixed! patch attached to simply keep our gentoo from full on blowing up. Problem with patches like this however is that as soon as it's out of sight it's out of mind and we forget where we disable security when we wanted it. However being that it's regexp code I don't mind so much myself it being disabled.
(In reply to comment #13) solar said: > Patch that disables ssp on the two regexp files in perl. Allows perl to > build and run while keeping ssp active everywhere else we can.

So, um, that sounds like the compiler is at fault. Shouldn't recursive functions work?
The perl-porters list mentioned this a couple weeks ago, seems to be barfing on a pointer deref. http://www.gossamer-threads.com/lists/perl/porters/193645
Is there anything that can be done about this temporarily. I've found that attempting to mask out perl-5.8.7 individually for some reason causes dependency graph breakages (previously it was reported at the manpages package, now it's being reported at the linuxwacom package) when attempting to update world. Having it unmasked means updating world has to be done manually, since this package won't compile, and it's been like this for a few weeks now. Does anyone have any suggestions that could help?
Sure, just specify your CFLAGS on the command line when emerging it, and make sure -fstack-protector isn't in them.
Hmmm, first off thanks for the speedy response. I dunno, it's possible I'm missing something along the way, because my emerge info does have hardened, pic and pie set, but from emerge info the CFLAGS and CXXFLAGS apparently do not list "-fstack-protector". Does this mean emerge info isn't showing the correct info, or does it mean that something else is stopping perl from compiling? Any further ideas?

You know.. There is a patch attached to this bug which works around the problem. Why dont you try that...
Thank you solar, the patch seems to work fine. I'm still confused as to how the stack-protector/no-stack-protector flag system works, however I guess this isn't the right place to find out. I hope the patch gets incorporated into a revision ebuild soon...
This only fails with -fstack-protector-all according to Peter S. Mazinger So the patch can probably be reduced to only disable -fno-stack-protector-all if we wanted to
That's incorrect, I have -fstack-protector only in CFLAGS and hit the failure.

the patch dont work for me. i saved it into dev-lang/perl/files/workaround.patch edited the perl-5.8.7.ebuild: src_compile() { # would like to bracket this with a test for the existence of a # dotfile, but can't clean it automatically now. src_configure epatch ${FILESDIR}/workaround.patch emake -j1 || die "Unable to make" } and do an `ebuild perl-5.8.7.ebuild digest` and it dont works. the same error appears. pls help! or i ask better, please eliminate the bug! thnx

About comment #27, IMHO you shouldn't patch after configuring but before. Just add somenting like : cd ${S}; epatch ${FILESDIR}/${P}-cflags-regexp.patch in src_unpack() it may work better
Changing Severity to a blocker. This prevents ~arch bootstrapping and can be observed in other distros that also use ssp. Perl team I know your pretty swamped, right now so if you don't comment on this bug in the next few days I'm going to assume that is the same as a thumbs up from you for me on merging the patch.

I have no problems with it - actually been working with someone on the mod_perl mess and the problems getting perl-* to compile on ppc, missed the part in this thread where you were good with the patch. I have no problems with you committing, or my committing, or being committed.
Thanks Michael Cummings. Patched perl up then. Reopen if problem continues. Please re-review if we need to add extra patches for this when 5.8.8 is hitting the tree. Changing resolution to TEST-REQUEST
It works for me.
It does NOT work for me. The patch is putting the -fno-stack-protector at the start of the compile command, but the -fstack-protector (from CFLAGS) comes after it and nullifies the effect of the patch. CCCMD = i686-pc-linux-gnu-gcc -DPERL_CORE -c -D_REENTRANT -D_GNU_SOURCE -DTHREADS_HAVE_PIDS -fno-strict-aliasing -pipe -D_LARGEFILE_SOURCE -D_FI LE_OFFSET_BITS=64 -fno-stack-protector -O2 -march=nocona -pipe -fstack-protector -fomit-frame-pointer -Wall
Note: The patch is intended to fix hardened toolchains compiles only. -fstack-protector in CFLAGS is beyond the scope of hardened and is simply unsupported as it can lead to miscompiles of many things. My guess is that your normal cflags are filling the $optimize variable, in which case you can probably edit the patch on your local box and change it to read as. + [[ $file == regcomp ]] && export optimize="${optimize} -fno-stack-protector" + [[ $file == regexec ]] && export optimize="${optimize} -fno-stack-protector"

No we can't/ should not do conditional patching. We need to add the stubs to the unsupported gcc-4.0 or just bump it to 4.1 Starting with gcc-4.1 ssp is included mainline.

(In reply to comment #49) > It's back again in 5.8.8. Pleas see comment #35. Is this what's happening in your situation? Perhaps you should try removing -fstack-protector-all from your CFLAGS.
This is occuring in 5.8.8-r5 removing -fstack-protector-all from CFLAGS does fix it. cflags.SH contains what appears to be the patch posted above, but does not match excatly. Changing cflags.SH to match patch did not fix problem for me. Not sure if this should be reopened or if removing -fstack-protector-all is the final fix.
(In reply to comment #51) > This is occuring in 5.8.8-r5 > > removing -fstack-protector-all from CFLAGS does fix it. The patch was not about -fstack-protector directly in the CFLAGS of a make.conf It was intended for hardened users. gcc:4 would probably need to take a whole new approach. This bug should be marked as closed
