Not personally, no. Sorry, but I'm afraid this really isn't an actionable bug report as it stands: we still don't have an effective way to reproduce, and it's far from clear that this is actually a bug in CPython as opposed to a bug somewhere in the BDSpyrunner code.

If you're able to produce (and attach to this issue) a minimal self-contained C++ file that exhibits the issue, that could help increase the chances that we can confirm the existence of a CPython bug. Even better, if you're able to diagnose the issue yourself to the point where there's a clear CPython bug to report, that's much more likely to lead to a fix. (And those two actions - producing a minimal example, and diagnosis, should be largely compatible.)
