BTW: Your patch also causes

Yes. Known. I bootstrapped a fix and had a box test it yesterday.
I'll look at the test results tonight and commit the fix if there are
no new failures (and this one is fixed).

This failure is caused by problems with dead jump tables. There's
another bug (with a PR filed for it) that is also related to dead jump
tables. The fix I have should fix both these cases.
