Symptoms

Declaring a global variable 'connect' in a Pro*C or OCI program fools the linker on some platforms, as Solaris (Intel and Sparc), Linux, and Tru64, and causes a core dump if a remote tns connection is to be made.

might let the linker complain about redefinition of connect(), or just pass and produce the output:

from my_connect
Connected to Oracle.
