[issue31626] Writing in freed memory in _PyMem_DebugRawRealloc() after shrinking a memory block

[STINNER Victor]

STINNER Victor <victor.stinner at gmail.com> added the comment:

For allocations larger than 512 bytes, PyObject_Malloc() calls PyMem_RawMalloc(). When debug hooks are installed, PyObject_Malloc() calls a debug hook which calls PyMem_RawMalloc() which calls another debug hook.
