[Bug c/37669] New: ice for legal code with -O2

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

I just tried to compile the Suse Linux package enlightenment-0.16.8.12-15 with
the new gcc version 4.4, snapshot dated 20080926.

gcc said

backgrounds.c: In function 'BackgroundGetUniqueString':
backgrounds.c:75: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
