@steveharter can you take a quick look here and see if this is something that needs to be fixed in 3.0? If not, move it out.

I was unable to repro locally. Run the unit tests 500x on both release and debug builds, as well as running the specific test (TestIsAssignable3) failing 5,000x on release. I ensured the COMPlus_* variables were set, max threads = 2 and parallel was on.

I inspected the call stack and there is no obvious reason for an AccessViolation: there is no native code interop or other direct memory usages. However the code documents that using System.Reflection.Metadata.MetadataReader with a disposed System.Reflection.PortableExecutable.PEReader can result in an AV, but that is protected against already.
