Thanks. I confirm crash(8) now exits cleanly when given the corrupted
vmcore after applying the patch.
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 :)
