No one else is seeing this, so I feel fairly safe in betting that
it's some bug in your own code. You didn't do something silly
like closing stderr, did you?
You might try setting a breakpoint at defaultNoticeProcessor in
fe-connect.c, and seeing whether control is getting there or not.
A stack backtrace from the core file would be helpful info as well.
