Ah yes, this is related. I reported v2010 below, but it looks like I was updated to this Insider Build overnight without my knowledge, and conflated it with the new installation R v4 this morning. I will continue to look into the issue with the methods Tomas mentioned.
It is interesting that a rare 5 years old problem would re-appear on current Insider builds. Which build of Windows are you running exactly? I've seen another report about a crash on 20190.1000. It'd be nice to know if it is present also in newer builds, i.e. in 20197.
I installed the latest 20197 build in a vm, and I can indeed reproduce this problem. What seems to be happening is that R triggers an infinite recursion in Windows unwinding mechanism, and eventually dies with a stack overflow. Attached a backtrace of the initial 100 frames of the main thread (the pattern in the top ~30 frames continues forever). The microsoft blog doesn't mention anything related to exception handling has changed in recent versions: https://docs.microsoft.com/en-us/windows-insider/at-home/active-dev-branch -------------- next part -------------- An embedded and charset-unspecified text was scrubbed...
