I compiled snapshot gcc-4.0-20040919.tar.bz2 and tried that compiler at our 
application. I get an ICE which occurs only at -O1 and above, not at -O0.

There are similar reports in bugzilla:

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=13186 is marked resolved/fixed

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=13674 is marked new with a comment 
from Andrew Pinski 2004-06-11: Hmm, I can no longer reproduce it with the 
testcases provided but I know that this is still a bug.

I can't judge whether this bug is a duplicate of 13674 or not, therefore I 
enter it as a new bug report.
