Comment:
short bit of analysis here. The tailcall happens without a problem. The
PIR compreg resets interp->current_cont to NEEDS_CONTINUATION. The NCI
VTABLE_invoke returns the old cur_opcode+2 destination instead of the
updated destination from the interp->current_cont. The runloop continues
execution past the end of the function, which leads to any number of
potential problems. I'm testing a fix for this right now.
