Doesn't reproduce for me on Oracle Linux 6.2.  I spent some time
getting as close to your configuration as possible.  I saw no failures
with various scenarios including invalid passwords, invalid connection
strings and expired passwords (https://bugs.php.net/bug.php?id=58477)

$ php -r '$c = oci_connect("cj", "cj", "mymachine/abc");
var_dump($c);' resource(5) of type (oci8 connection)

Some comments:

1. Oracle Instant Client 10.1 is very old.  Unless you need it for a
reason reason, use at least 11.2.
http://www.oracle.com/technetwork/topics/linuxx86-64soft-092277.html

2. Oracle DB & client isn't certified on RHEL 6, so all bets about
behavior are off.

3. Why build only OCI8 shared?

4. The configure line has "--enable-mysqlnd" but none of the MySQL
extension options say to use mysqlnd, so the MySQL client libraries
are still being used.

1. used the new oracle client
2. nothing i can do about it :)
3. compiled into PHP, not as module
4. removed the option

Same error, i recompiled PHP without OCI.
it worked using: pecl install oci8
