runtime: AccessViolation on the gc phase
Hello,
AccessViolation (AV) was raised a couple of time on the our app under .net472 at a different state of GC, but unfortunately I can’t attach dump of app. So I wrote a simple app (AccessViolation.zip) that try to emulate work with memory as is doing our app. Simple app was running in 4-6 instances in parallel on the 16gb of RAM under 64bit preferred in Debug configuration under Win10 and a couple of dump was created when AV was raised:

Thanks for this report. There is probably something about the underlying issue that makes some machines much more likely to see a crash compared to others. I have been fanning out the repro (on both net472 and net50) for the past few days across a few different execution patterns (i.e., varying parallelism and timeout), and haven’t seen any crashes yet.
I’m going to spend more time digging in the dump files to see if there are any clues about what went wrong when the crashes did occur.
