Looks very similar to  issue 728616  which happened in a similar time frame. 

Also, looking at the stack traces on the fuzzer I see tons of other leaks.

It looks like the same issue?
This looks identical to 728616 to me. Suggest duping on it.

Yeah, looks like the same issue, thanks! As it happens again and again, we probably need to find some solution, e.g. disable leaks detection for AFL as suggested in https://bugs.chromium.org/p/chromium/issues/detail?id=728616#c8
