This is still on the open items list[1]. Given this is a
user-triggerable crash and we are approaching PG15 Beta 1, I wanted to
check in and see if there was any additional work required to eliminate
the crash, or if the work at this point is just optimization.
If the latter, I'd suggest we open up a new open item for it.
Thanks,
