[issue31912] PyMem_Malloc() should guarantee alignof(max_align_t)

Florian Weimer added the comment: max_align_t is a bit of a kitchen sink and will specify larger and larger alignment in the future, e.g. 32-byte alignment for a complex _Float128 type (a pair of two _Float128 variables). The alignment is also not generally useful for allocations whose size

[issue31912] PyMem_Malloc() should guarantee alignof(max_align_t)

New submission from Stefan Krah : This is related to #27987 and #20064 and perhaps the pymalloc patch from #18835. I think PyMem_Malloc() should guarantee alignof(max_align_t). It actually did before the "#define PYMEM_FUNCS PYOBJ_FUNCS" optimization, so we have a sort of regression here.
