[FieldOffset(0)]
public short X;
[FieldOffset(2)]

}We should not allow this to load.

I have the CoreCLR fix for this. The Mono changes are bit more complex and taking some time.

FWIW, Mono doesn't even detect #12842.
There's not even a bug for it because I don't think Mono ever ran a Pri-1 CoreCLR test pass (the regression test is Pri-1). If you make your regression test Pri-1, you can save yourself some work. It's not a Pri-0 scenario.

@MichalStrehovsky I've spent most of the day getting Mono in the right state. I am hitting issues now that are really confusing. I am close to doing what you suggest. Likely will make the call tomorrow.
