Is there some place where I can pick up the latestest of your fuzzer?

PeterZ has trouble reproducing the corruption locally - I'd like to 
run it too, maybe I have hardware that triggers it more readily.

Plus it would be nice to get your latest .config as well, that you are 
using to generate this crash. (You can send it in private mail as well 
if you wish.)

Thanks,

	Ingo
