OSX-ARM64 Investigate Hello World failure.

[sdmaclea]

With #40435,

HelloWorld fails like this:

   at System.NullReferenceException..ctor()
...
Repeat until stack overflow

The amusing thing here is that InternalGetResourceString protects itself against recursive lookup - unless it is specifically a failure within List<T>.LastIndexOf

One would think that would be rare, but #40073 hit it for another reason.

We probably should fix that in InternalGetResourceString, not that it would solve the problem here.

Thanks @danmosemsft. Root cause of #40073 was a bad S.P.C.dll. This could be the same issue. As I have been trying to work around #41120, so my S.P.C.dll build may not be right.

With a proper S.P.C.dll as mentioned in #40435 (comment), the hello world exception now looks like an interop issue.

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

Fixed in #40435
