i have entered a bug for gimp (#309170) in which gimp would crash when i opened
an image of the same resolution as my current screen. in that situation, gimp
automatically downscales the image to fit on the screen.
when gimp was compiled with -mfpmath=sse the crash would occur. on recompiling
without that option, gimp operates correctly.
the complete thread for the bug can be found at
http://bugzilla.gnome.org/show_bug.cgi?id=309170, however you can find the
details for my system and the compilation options below:

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).

never got any feedback from the gimp folk to provide a test case. so i will
just stick to compiling without -mfpmath=sse as a work around.
invalid doesn't seem to be the right sort of resolution state, since there is a
bug. maybe suspended would be better, recognizing that there is a bug, but that
it probably won't be fixed.

Without a test case, the bug report is invalid even if you're seeing a
legitimate bug. That's why it is closed as INVALID. Bugs are put in
the SUSPENDED state if the problem is reproducible but not fixable.
