@dyung https://github.com/llvm/llvm-project/pull/175537 adds a new diagnostic that should help to figure out what's going on with that failure. I'll land tomorrow morning Sydney time, or you're welcome to merge before then if you'd like. I'm hoping to get at least one run in with that diagnostic applied to see if we can figure out where the wild address for `main` is coming from.

Once we've got that info the testcase can be disabled or removed for now.
