[Bug c/30564] New: ice for legal code with -O3

["dcb314 at hotmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

I just tried to compile Suse Linux package lynx-2.8.6_rel2-23
with the GNU C compiler version 4.3 snapshot 20070119.

The compiler said

gcc -DLINUX  -D_GNU_SOURCE -DHAVE_CONFIG_H -I../.. -I../../src
-I../../src/chrtrans -I../../WWW/Library/Implementation -I../../   -O3
-fmessage-length=0 -D_FORTIFY_SOURCE=2 -pipe   -c ./makeuctb.c
./makeuctb.c: In function 'main':
./makeuctb.c:253: internal compiler error: in extract_range_from_assert, at
tree-vrp.c:820
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

Preprocessed source code attached. Flag -O3 required.
