As a maintainer of Hypothesis and sometime-fuzzing-researcher, hopefully sharing my perspective might help. Firstly, fuzzing and property-based testing are clearly related fields! Personally I tend to divide them more by the UX than underlying tool: PBT tends to be quick (seconds), done by dev

Coverage-guided fuzzing is fundamentally just a technique that iteratively generates input that explores more code relative to the possible execution space of the code targeted. What the fuzzer gives you to play with is a byte-array that you can massage in any way possible and pass it into the

Hi, Thank you Matthew and Petr - you pointed in the right direction. The 2016-dicussion and Petr's explanation made it clear what the problem was. Petr Viktorin: > Does Racket's ffilib support RTLD_GLOBAL? Yes. All I had to do was to change (ffi-lib path-to-libpython) into (ffi-lib path-to-lib
