Actually that patch fixes all the crashes I found with my previous round of black box fuzzing on x86_64 (using zzuf if 
anyone is interested). I am currently playing with bunny (http://code.google.com/p/bunny-the-fuzzer/) but I am a bit 
doubtful it will find anything useful in any decent amount of time without some manual work, oh well CPU time is cheap :)
