------- Additional Comments From giovannibajo at libero dot it 2005-07-04 15:34 ------- To produce a testcase, you could try extracting the routine that is miscompiled and attach it to this bug (in a compilable form, so preprocessed with all needed headers). I believe the GIMP folk can help you with this.
It might be that the bug is visible by just looking at the assembly code generated by the compiler (-S). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=22289
