TypeLoadException for struct with static nullable field


struct MyStruct {
    public static MyStruct? Value;
This will throw a TypeLoadException at runtime.
Removing the ? makes it work fine.

Note that the old compiler incorrectly refused to compile this at all.
(since the field is static, this isn't actually a cycle)

This is a know limitation of the CLR type loader. The compiler compiles the code without reporting an error since it's correct according to the C# specification and it actually works on some CLI implementations.
