I've already tested it with -O2 -fno-strict-aliasing without success. I'll test
it with -O0.

I've tried it with gcc 4.2.4 and it works perfectly, so it have to be caused by
some change between 4.2.4 and 4.3.2.
I'll try to use svn to find out which commit causes this.

I've recompiled gcc 4.5 snapshot with the patch included. The file
bilateral2.ii compiles perfectly.
Thank you, you're doing a great job.

The strange thing is that when I copy the problematic part (even with

thanks to Ketling (one guy who helps me with identifying the bug) there is more
