ecpg program getting stuck

Hello List

I have a program that worked fine in 7.4.19. I am in process of upgrading
to 8.3.1 and my program runs for a while and then hangs. I used gdb
to attach to the process and it shows the following backtrace which
shows it
going into the libpq library and getting stuck. Anybody have any ideas on
how to proceed?

I don't see anything in the postgres error log file.

(gdb) bt
