AccessViolationException sometimes happens in F# compiler #110012

Closed 0101 closed 1 day ago

0101 commented 1 day ago

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?
