Have you changed something about how the compiler invokes setjmp/longjmp for exception handling?

We didn't used to get these errors with -O3.  I don't know what has changed with the compiler backend, but something new is happening.  We should check the logs to see the last time I pushed through -O3, and figure out what changed since.

And one error running the result that I didn't look into.
