https://helixre107v0xdcypoyl9e7f.blob.core.windows.net/dotnet-runtime-refs-pull-87311-merge-c943aeab4f7d47da9e/PayloadGroup0/1/console.28b15c42.log?helixlogtype=result shows a heap verification error. however the data shown in the dump doesn't really make sense. the assert is saying total_objects_verified should be the same as total_objects_verified_deep and is not but the value of total_objects_verified exceeds the # of bytes on the heap. this is at a place where while the foreground GC is happening the BGC thread could be changing the state from planning to free, however, this should not affect the results (they should still be the same). rerunning the workitem.
