RTS crashes

[Simon Peyton Jones]

In my private build of !12492 I'm getting some assertion failures in
CheckUnload (see below).

This can't possibly be my fault!   I don't know if CI perhaps has these
assertion switched off, so only I am seeing them?

I'd open a ticket but it may just be my bad, somehow

Any ideas?

Simon
