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
