I looked up oci8_driver and only clue I got when I tried to cause error is that method _error_message() at line 488 returns nothing, and $array array is just empty, no "message" key within.
Error reporting is very important to me because there is much bigger bug that is showing up randomly.
Once in a while 'select' operation fails and produces error message, but immediately after refreshing page it just past clearly like nothing happened. It scares me out and i can't catch even error message.
If I can help in any way, please just tell me, if required you can contact me at email for any further tests you need or just post it here.
