Hm, I see the assert failure, but this example doesn't seem to crash
when asserts are off, and I'd not expect it to: it should either work or
elog(ERROR) in ExecRestrPos.  So maybe you've found more than one issue.
Can you get a stack trace from a case that causes a non-assert core
dump?  (You don't need to rebuild, just set debug_assertions = 0 while
testing.)
