The addresses there are weird.  tupdesc1 is neither a stack address nor a heap
address; it may be in a program text section.  tupdesc2 is a stack address.
In the earlier stack trace from
https://postgr.es/m/CANFyU94Xa8a5+4sZ7PxOiDLq+yN89g6y-9nNk-eLEvX6YUXbXA@mail.gmail.com
both tupdesc1 and tupdesc2 were heap addresses.

Thanks.  Please try the attached test version, which avoids exiting too early
like the last version did.
