bpo-35368: Make PyMem_Malloc() thread-safe in debug mode (GH-10828)

2018-12-03T11:29:29+00:00

When Python is compiled in debug mode, PyMem_Malloc() uses debug
hooks, but it also uses pymalloc allocator instead of malloc().
Problem: pymalloc is not thread-safe, whereas PyMem_Malloc() is
thread-safe in release mode (it's a thin wrapper to malloc() in this
case).

Modify the debug hook to use malloc() for PyMem_Malloc().
