Though random module doesn't receive frequent changes can you please add the relevant lines in the description or the relevant commit with the corresponding line number in the report with a description. On master with commit [0] line 295 calls PyMem_Free(key); and then calls goto Done where PyMem_Free(key); is again executed which I assume is the report. [0] https://github.com/python/cpython/blob/d73ac0eba992a33992210915739d73250bf6d38d/Modules/_randommodule.c#L295 | |||

line 295 calls PyMem_Free(key),then "key" was freed again in line 317 which causes the bug. | |||
