ODBC and multiple connections under fedora

I can't seem to successfully open >1 DB connections via ODBC, to
PostgreSQL, under Fedora. It seems to seg fault in the oddest of
places. This code has worked fine on RH Linux <=9.

Is there something I'm supposed to enable in the odbcinst.ini file
for multiple connections to work under Fedora?

A small test program and my .odbc.ini file is attached. The program
runs fine if you comment out the second connection. isql on the DSN
also runs fine. The program runs fine on RH Linux <=9.

Thanks.
