This caused a SegFault in TestFoundation.

It’s possible that compiler changes caused it, but it seems best to rule out the smaller changes to corelibs-foundation first. Lily, are you able to reproduce this?

I’ll retry it locally tomorrow.

It would be so, so, so much better if we had a solution to get stack traces out of CI crashes.
