[Python-Dev] libffi embedded in CPython (original) (raw)

well, the problem is essentially that libffi gets patched (e.g. for ARM) and it does not make it's way to CPython quickly. This is unlikely to be a security issue (for a variety of reasons, including ctypes), but it's still an issue I think. Segfaults related to e.g. stack alignment are hard to debug

It has some sort of Windows related patches. No one seems to know whether they're still needed for newer libffi. Unfortunately, ctypes doesn't currently have a maintainer.
