Looks like the bootstrap compiler crashes? It could be due to an old bug in the bootstrap toolchain.

This should be fixed by #44505, assuming that that actually happens as planned for Go 1.19.

Builders are now on Go 1.17. This should stop happening.

There have been no occurrences of this since the 2022-03-02 log @bcmills linked above, and we have reason to believe this is fixed, so I'm going to close this. If it does happen again, we can reopen.
