I would try to make a compilable example that doesn't require any external
data but still causes the crash. I.e. generate an image programatically so
someone on the mailing list can copy+paste+compile+run your code. This will
allow them to a) see if it also crashes for them and b) eliminate
the uncertainty about what is going on with the input images to see if the
problem is being caused by your data (which would still need an
explanation) or if there is something wrong with the code itself.
