While the commit b484d5606ca76f9bbd0f5de7a6ef753400213e94 fixes a crash on OpenBSD and makes the code "correct" on any platforms, I still see it as a feature regression. Detecting buffer overflow and using freed memory are feature of debug hooks. https://docs.python.org/dev/c-api/memory.html#c.PyMem_SetupDebugHooks So yes, debug-realloc.diff is interesting.
