It'll take me a while to come up with a dataset I can distribute that
causes it. My first pass at fake random data didn't seem to trigger it,
and I can't divulge the real data.
I can poke with gdb, is there a guide for what to look for somewhere?
I know my way around a debugger, but not the postgres internals all that
well.
