AccessViolationException sometimes happens in F# compiler #110012
Description
Description
F# compiler sometimes crashes for me when compiling projects (in the fsharp repo itself).
Here's the dump from the process: https://microsofteur-my.sharepoint.com/:u:/g/personal/petrpokorny_microsoft_com/ETWIINZkTGBIiQx8ob4KIzoBdoAidVakBTvexFGPNnv_BQ?e=gMb5If
I cannot really tell what causes the exception.
Reproduction Steps
git clone dotnet/fsharp
build.cmd -c Debug
Expected behavior
fsc.exe doesn't crash
Actual behavior
fsc.exe sometimes crashes
Regression?
Yes
Known Workarounds
Try again.
Configuration
Windows
SDK 9.0.100
Other information
This thread's stack trace seems suspicious, probably that's where the AVE happened?
