I think #112711 will fix this.

@amanasifkhalid how did you determine this? I tried reproing locally with no success, and the dump is not enlightening/

I'm able to get a consistent repro using the work item's runtime build, and by running the Loader\binding\assemblies\generics\arilistienum\methods\exceptions\exceptions.cmd test directly with DOTNET_TC_OnStackReplacement_InitialCounter=1 and DOTNET_OSR_HitLimit=1 set. If I set DOTNET_JitObjectStackAllocationArray=0 as well, the failure goes away. This is on win-x64.

If this doesn't repro after this weekend's outerloop pipeline runs, then maybe we ought to close it.

It didn't repro.
