Unfortunately, I do not know what this means, so I haven't been able
to extract a simple test case. FWIW, this didn't happen in r11470,
though r11470 has a different problem relating to error handling --
signalling an error corrupts a Sub PMC, trashing its vtable slot.
Any and all hints gratefully accepted.
