In getargs.c, in addcleanup_convert(), PyCapsule_SetContext() is called with a second argument "int (*destr)(PyObject*,void*)", but it really expects a "void (*PyCapsule_Destructor)(PyObject *)".
I'm not sure it's a good idea, although the ABI may be lenient enough on common architectures (?)...

I fail to see the problem. The context is a plain void*, not (necessarily) a function pointer, and getargs uses it with the same type it put in. Why do you think PyCapsule_Destructor is of relevance?

Woops, sorry. Apparently I messed up PyCapsule_SetContext and
PyCapsule_SetDestructor when reading the function declaration.
