Sounds like it should mostly work.  If "new" has been hacked to return NULL instead of throw an exception, you are going to get crashes in those cases.  But that is unlikely to happen so long as you don't ask the library to do too much buffering (like reading tiled images with Imf::InputFile).  You could override the new operator to try to exit the program gracefully instead of returning NULL and crashing.

Yeah, I think the fuzz tests are pretty platform-independant.  It's not really important that they work on your platform.
