make[3]: *** [cmd5.lo] Fehler 1


Solution: CFLAGS must be reduced to CFLAGS="-march=athlon-xp -m3dnow -O3 -pipe"
(see used CFLAGS in "additional information") and it will emerge without
problems.

Reproducible: Always
Steps to Reproduce:
1. Set aggressive CFLAGS
2. emerge dclib
3. Set safe CFLAGS

I have the problem if using gcc-3.3.3. I only did 'gcc-config 2' (2=gcc-3.4.3)
and 'source /etc/profile' and it compiled fine even with CFLAGS="-O3
-march=athlon-xp -mfpmath=sse -mmmx -msse -mno-sse2 -mno-sse3 -m3dnow
-funroll-loops -fomit-frame-pointer -pipe".

I have the same error, but only with hardened gcc-3.4.3 (vanilla gcc-3.4.3
works fine) and CFLAGS="-march=athlon-xp -O2 -pipe -frename-registers
-fomit-frame-pointer ".

I've attached the pre-processed code.  Though the original source file
(http://www.neuromancy.net/viewcvs/Mantra-I/src/storage/xml.cpp?root=mantra&rev=1.40&view=markup)
is only 1400 lines (including comments), when I try to compile this code, I've
seen it use >330mb of RAM.

Could everyone who has this problem, please post combinations of:

1) Compiler version
2) CFLAGS

which cause the ICE?

Avoid sweep string variable ICE; issue a warning when it occurs

Ok; here goes nothing.  Patch is for gcc-3 (NOT gcc-4 where everything is
different).  It avoids the ICE that occurs in the affected packages, and
instead issues a warning.

It should generate working executables, however it may mean that one of the
steps SSP takes to protect functions is not taken properly.  In other words,
while it's better than switching off SSP completely, it may leave some
functions partly unprotected.

To try it out, add this patch to sys-devel/gcc, and remove 'filter-flags
-fstack-protector' from the ebuilds of the affected packages if present (all in
your overlay or course).

Please report here if any of the packages that previously ICE'd in
sweep_string_variable still ICE, or if the application builds but doesn't run
properly.

Any final versions should probably be wrappered in #ifdef __i386__ as it seems
this only effects x86 arch according to kumba

I applied Kevin's patch to gcc-3.4.5 and it fixed up my compile problems with
both versions of hylafax currently in the tree (4.2.3-r1 and 4.2.4). These
problems are described in bug 109833. Thanks :)

Only tested on a Mips box atm.  I'll have to reboot my sparc64 box (it's
deadlocked) and test it later on to see if it's affected as well.  Will update
on how that works out.

preprocessed source that fails to compile

compiles with gcc 3.3.6 (hardened), and gcc 3.4.4-hardened-nossp.
It fails with 3.4.4 (hardened).
I did not apply any optoins, just tried g++ -c failed.cc

Adding -O2 optimises away the ICEs (i.e. 'g++ -O2 -c failed.cc' compiles
cleanly).

As well as -O3 and -Os.

I patched boost to always optimize (even for debug libraries), and I will see
if it builds.

another failed source

This one is from libfpx, and compiles with -fno-stack-protector.
A few -O options I tried do not affect it, and it does not compile with just
gcc -c (gcc 3.4.4).
gcc 3.3.6 compiles it.

*** Bug 122349 has been marked as a duplicate of this bug. ***

The gcc patch also fixes boost and libfpx.

Mark,
I've committed my change to protector.c to remove this ICE for 3.4.6; if you
could roll it up if you release 3.4.6 again that'd be great.

you want a revbump ?

ultimately, yes please - but I'll do #104754 (SSP specs consistency) first to
avoid unnecessary bumps (it's top of my list), and maybe if we can find what's
wrong, a fix for #133301.

Is it possible to post patch somewhere? I want to use it as overlay as i'm need

It's already attached to this bug - see the 4th attachment "Avoid sweep string
variable ICE; issue a warning when it occurs" (actually the final patch is a
little tidier, but that's just cosmetic).

SpanKY - when you get chance, can you do the bump including also the fix for
#104754?  The patches for this bug and #104754 are in the patchset CVS in ssp
and piepatches directories respectively.  I did a trial-run of a bump with
gcc-3.4.6-ssp-1.0.tar.bz2 and gcc-3.4.6-piepatches-v8.7.9.tar.bz2 and it seemed
to go fine.  Or give me the nod if you're happy for me to do it.

Sorry, i was confused about its creation date. Thanks a lot.

feel free to push out ssp/pie fixes for gcc-3.x ... if you need something, just
grab me on irc

ok; sys-devel/gcc-3.4.6-r2 is in, with this fix

gcc-3.4.6-r2 emerges ok, pdns-recursor emerges ok, everything is working great.
Thank you guys.
