Message 191881 - Python tracker

> Can we get a full stack trace (for the C stack not the Python one) for the failure?

Yes, using a debugger on Windows x64. I'm waiting for a renewal of my MSDN account to get Visual Studio (full version, not the Express version limited to 32-bit).

Until this, I enabled faulthandler in subprocesses created by test.regrtest and test.script_helper because it may help this issue, but also others future crashes.
