"I tried to build CPython on 64-bit OpenBSD. It was built successfully, but tests crash."

It's the first time that anyone complains about _PyMem_DebugRawRealloc(). The behaviour seems to be very specific to OpenBSD.

Even if the current code is "weird", it works very well and is effecient.

I proposed attached PR 4119 which makes _PyMem_DebugRawRealloc() behaves correctly: erase bytes *before* calling realloc(), but keeps a copy if realloc() fails. My PR only changes the behaviour on OpenBSD. It keeps the current behaviour (erase bytes *after* realloc, if realloc succeeded) on other platforms for performance reasons.
