I think I'm hitting the same bug as the reporter.

Please submit a full bug report,
with preprocessed source if appropriate.
See <http://bugs.gentoo.org/> for instructions.

This is from a gentoo ebuild, but no patches are being applied.  I'm using the
gcc-4.4 snapshot from 20090306, and argp-help.c is from a glibc-2.9 snapshot
from 20091201.

I used -save-temps to get a preprocessed file (I'll attach momentarily) and did
a little trial-and-error experimenting.  Here's what I found:

gcc -c argp-help.i -o argp-help.o -O0 : succeeds
gcc -c argp-help.i -o argp-help.o -O1 : fails
gcc -c argp-help.i -o argp-help.o -O1 -fno-inline : succeeds

This is on an i686 (athlon-xp) machine, but I get the same failure on my x86_64
(amdfam10) machine.

Here's my output from gcc -v (on the athlon-xp machine):

OK, maybe I should slept before I submitted this.

1.  The glibc-2.9 snapshot is from 20081201.  I am not capable of time travel.

2.  I successfully compiled this same glibc-2.9 snapshot with the gcc-4.4
snapshot from 20090220.  Hopefully this helps.

[Bug c/39486] New: ICE with gcc 4.4-20090313 when compiling elfutils-0.140 with -g

2009-03-17 Thread cneil at yahoo dot com 
When compiling elfutils-0.140, I encountered the following ICE:

x86_64-pc-linux-gnu-gcc -D_GNU_SOURCE -DHAVE_CONFIG_H -I. -I.. -I. -I.
-I./../libelf -I./../libebl -I./../libdw -I.. -I./../lib   -Wall  -Wshadow

Please submit a full bug report,
with preprocessed source if appropriate.
See <http://bugs.gentoo.org/> for instructions.
make: *** [link_map.o] Error 1

I'm using the gcc 4.4-20090313 snapshot.  I get the same error on both i686
(athlon-xp) and x86_64 (amdfam10).  I used -save-temps, and started some
experimenting:

gcc -c link_map.i -o link_map.o -std=gnu99 -O1 -ggdb : fails
gcc -c link_map.i -o link_map.o -std=gnu99 -O1 -g : fails
gcc -c link_map.i -o link_map.o -std=gnu99 -O1 : succeeds

Removing -ggdb allows the build of elfutils-0.140 to successfully complete.

Here is the output of gcc -v from my x86_64 machine:
