How to get the crashes from AFL directly.

[mkb]

Hello. I am fuzzing a target with low stability using a persistent mode, and I got some crashes that I cannot reproduce. Is there a way to store the segfault during fuzzing via AFLPlusPlus and potentially get some debug info from it too?

Hi mkb,

Try AFL_DEBUG=1. I asked the same question once:

Thanks,
