*** Bug 377213 has been marked as a duplicate of this bug. ***
I saw a workarround for this on github, consider taking it a look: https://gist.github.com/1057203
I'll braindump here what i have found out. It's likely caused by this change in glibc: http://sourceware.org/git/?p=glibc.git;a=commitdiff;h=fcabc0f8b185f9e0a9289720be5ede6c39b3bf21#patch5 Why i think so: The simplest test case i was able to get is the following: sf dl # pwd /var/tmp/portage/dev-lang/ruby-1.8.7_p334-r2/work/ruby-1.8.7-p334/ext/dl sf dl # cat mkfoo.rb # -*- ruby -*- # we emulate emulate # require 'mkmf' # > @orgerr = $stderr.dup # > @orgout = $stdout.dup # orgout = $stdout.dup #more than 4kb, seems to be a glibc's buffer printf("1\n" * 2048) printf("2\n" * 32) sf dl # ../../miniruby mkfoo.rb > a.foo; head -n 2 a.foo 2 2 The head is overwritten. Let's look at the strace log: sf dl $ strace -etrace=open,write,close,lseek,dup,dup2,execve ../../miniruby mkfoo.rb > a.foo; head -n 2 a.foo ... [snippet] ... [1] dup(1) = 3 lseek(3, 0, SEEK_CUR) = 0 lseek(1, 0, SEEK_CUR) = 0 lseek(3, 0, SEEK_SET) = 0 [2] write(1, "1\n1\n1\n1\n1\n1\n1\n1\n1\n1\n1\n1\n1\n1\n1\n1\n"..., 4096) = 4096 [3] lseek(3, 0, SEEK_SET) = 0 [4] close(3) = 0 [5] write(1, "2\n2\n2\n2\n2\n2\n2\n2\n2\n2\n2\n2\n2\n2\n2\n2\n"..., 64) = 64 2 2 Here we see: [1] fd=3 is an alias of fd=1 (stdout) [2] part of print()s is written to disk [4] 'orgout' is garbage collected out (program shutdowns) [3] and right before fclose() glibc "restores" pointer of file descriptor (offest for fd=3 is 0, as nobody written to the dupped fd). [5] last bits of stdout are flushed to fd=1, but it's descriptor is shifted, so last write overwrites head I don't know how to fix it properly. I see such variants: 1. all mkfmrb users must call $stdout.flush at the end of file 2. Ruby's implementation of IO#dup(io.c:rb_io_init_copy:rb_fdopen) and it's finalizer (io.c:fptr_finalize:fclose) should not use fdopen/fclose. Or should restore position properly. 3. fix mkfm Logger module Thus, the workaround for this particular case is the following: --- mkcallback.rb.orig 2011-08-10 19:20:59.338487021 +0300 +++ mkcallback.rb 2011-08-10 19:20:39.154739353 +0300 @@ -54,3 +54,5 @@ print(mkfunc(t, n, 15), "\n\n") end } + +$stdout.flush
(In reply to comment #4) Thanks for digging in! > Thus, the workaround for this particular case is the following: > > --- mkcallback.rb.orig 2011-08-10 19:20:59.338487021 +0300 > +++ mkcallback.rb 2011-08-10 19:20:39.154739353 +0300 > @@ -54,3 +54,5 @@ > print(mkfunc(t, n, 15), "\n\n") > end > } > + > +$stdout.flush But if we do this then we fix the installation of ruby itself, but code using ruby will behave differently depending on the glibc version underneath it and thus "randomly" break things. Option 2 (fix IO::dup) is probably the solution we should aim at, but also something that is outside our own scope. If someone wants to work on this it's probably better to do so on the upstream bug directly.
The conclusion appears to be that this is a bug in glibc instead. See http://sourceware.org/bugzilla/show_bug.cgi?id=12724 Reassigning accordingly.

Upstream bug report, with patch: http://redmine.ruby-lang.org/issues/5108
Builds ok with the patch... but I don't actively USE ruby myself, but: Tue Nov 29 18:49:02 2011 >>> sys-libs/glibc-2.14.1-r1 Thu Dec 1 09:11:23 2011 >>> dev-lang/ruby-1.8.7_p352 # ruby --version ruby 1.8.7 (2011-06-30 patchlevel 352) [x86_64-linux]
(In reply to comment #11) > Upstream bug report, with patch: http://redmine.ruby-lang.org/issues/5108 Already linked to the bug in the URL field. Also, as mentioned in comment #5, the patch would only fix the ruby build but leave users of this module open for similar, but probably much harder to detect, problems.

Created attachment 294893 [details, diff] 0068_all_glibc-2.14-glibc-revert-fseek-on-fclose.patch try this patch; it comes from opensuse. place it in /etc/portage/patches/sys-libs/glibc/ and re-emerge glibc. see if it fixes the troubles with ruby.
Works here!
queued it up then http://sources.gentoo.org/gentoo/src/patchsets/glibc/2.14.1/0068_all_glibc-2.14-glibc-revert-fseek-on-fclose.patch?rev=1.1

I have sys-libs/glibc-2.14.1-r1 and I still have this problem. Has the patch been inserted in portage without a version bump or is it still in approval process? I also noticed that dev-lang/ruby-1.9.3_rc1 compiles fine without patched glibc.
Ditto comment 22. Me too. I still have this problem building ruby-1.8.7_p352 with glibc-2.14.1-r1 on an old x86 machine, but it worked on my newer amd64 machine.
The patch isn't in glibc-2.14.1-patches-2.tar.bz2, so I guess we need to wait for glibc-2.14.1-patches-3.tar.bz2 and sys-libs/glibc-2.14.1-r2. My previous comment 23 saying ruby built okay on my amd64 machine with glibc-2.14.1-r1 was incorrect; I should have checked my emerge logs first!
*** Bug 395137 has been marked as a duplicate of this bug. ***
This bug was resolved as "fixed" over a fortnight ago. Any news on when a patched version of glibc >=2.14.1 containing the fix will be released to portage?

Is this a bug in glibc, as (at least on my ~x86 system) glibc 2.14.1-r1 seems to have the that bug fixed as the sample program in the bug runs successfully (ie none of the asserts trigger). So if anything it looks like the fix to the glibc bug has triggered a problem in ruby, so should it not be fixed in ruby rather than reverting the change to glibc?

Patch attached to bug #396393 fixes the problem with ruby, IMHO.

Nope, while the patch in glibc fixes one aspect, it doesn't fix another, leaving a non-POSIX solution in place that ruby happens to trip up. This needs to be reverted or fixed properly in glibc, which is what Mike already has done (but not added to our main tree yet).
(In reply to comment #39) > Patch attached to bug #396393 fixes the problem with ruby, IMHO. It doesn't. True, it let's ruby's own build process continue, but this still leaves broken code around that will trip up other people's code. I'd rather ruby doesn't build at all in that case.
