Oh, sorry.
It was a part of source from rawstudio which used to work correctly but since

__USE_GNU) to a different file it works.

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.

patch causes this problem.
Anyway I've done more investigation to the problematic code.
The problem actually

I've forgot to post info about gcc 4.2.4:
$ gcc -v

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

Thanks a lot. Actually I'm a very beginner in C++ and I don't understand this
code a lot.

thanks to Ketling (one guy who helps me with identifying the bug) there is more
progress:
high = (uv & 0x8000) != 0; is always zero.
