Description
Bug report
Bug description:
MD5 and SHA* objects free their HACL* state before they are GC-untracked. In addition, I believe that MD5 and SHA* objects do NOT need to actually be GC-tracked because they do not contain anything other than a plain HACL* state pointer which is not a Python object (but that's a separate issue).
