------- Comment #2 from cneil at yahoo dot com 2009-03-09 09:58 ------- I think I'm hitting the same bug as the reporter.

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): Using built-in specs.
