You seem to have a rather badly broken build there :-(. What's the
platform exactly, and what compiler did you use? Can you rebuild
with debug support enabled so you can get a stack trace that's
actually useful?
If it just started happening, I'd speculate about a corrupt executable
file for psql or libpq. I doubt it's got anything to do with the server
side.
