R SVN 89661 Causes RStudio to crash

[Avraham]

I compiled R SVN 89661 and it passes make check-all and Rgui.exe loads, but Rstudio crashes, even daily+392. I guess there is a commit after 89649 which causes an unrecoverable error. I'm hoping tomorrow's build handles it, but I'm posting here just in case. Thank you

The problem still exists with daily 410 for Windows 11:

In the event that there is an issue for a while, would anyone know the most recent commitof R-devel that does NOT suffer from the problem? The SVN I was using until now was 89309, but that is ancient. Thank you.

This is not a solution, but the bug is being handled in the Rstudio GitHub repo, so I will close this.

Please see:
