[Bug c/17558] New: internal compiler error: in merge_alias_info, at tree-ssa-copy.c:182

["olh at suse dot de" <gcc-bugzilla at gcc dot gnu dot org>]

current gcc fails to compile xorg-x11, -fno-unit-at-a-time is a workaround:

pomegranate:/usr/src/packages/BUILD/xc/lib/font/Type1# /usr/lib/gcc/powerpc-suse-linux/4.0.0/cc1 -fpreprocessed spaces.i -quiet -dumpbase spaces.c -auxbase-strip unshared/spaces.o -O2 -version -fsigned-char -o spaces.s -v
