Hi,

there were no changes to that area of plpython after March 2011.

Could you try to see if the error also appears if you run your app with
current PostgreSQL HEAD (both the server and plpython)?

Which Python version is that? You can get that info by running:

do $$ import sys; plpy.info(sys.version) $$ language plpythonu;

Could you try to extract a self-contained example of how to reproduce
it? If the bug only appears under your application's specific workload,
perhaps you could try running it with Postgres compiled with -O0,
because compiling with -O2 causes the gdb backtrace to be missing
optimised out values and inlined functions?

Cheers,
Jan
