Description

One of our test jobs threw the following exception:

Fatal error. System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

The job passed when re-ran. ARM runner, .NET 9. Unfortunately I can't provide a repro, but I thought I'd leave this here just in case.

Reproduction Steps

N/A, sorry, happened only once in a test job in GH actions and then it passed.

Expected behavior

No access violation.

Actual behavior

Access violation

Regression?

No response

Known Workarounds

No response

Configuration

.NET 9
Linux
ARM runner

Seems arch specific insofar as the exception mentions Mach-O specific code.

Other information

No response
