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.
