That's a smoking gun then. Your GCC builtins don't work.

Hm. You could look at the regression.diffs file to get more info
about what's happening. But TBH, if you don't have GDB working
yet, it doesn't seem like making Postgres work is a higher priority
problem than that.

Once you've got GDB working, I'd be willing to help investigate,
if you can give me ssh access to a RISC-V box with a devel
environment installed. Before that, it seems like a pretty
back-burner problem.
