Operating system: Linux + libc6 2.0.7
PHP version: 3.0 Latest CVS (05/11/1998)
PHP Bug Type: Oracle related
Bug description: Core dump in _ora_ping
I'm running Oracle 8.0.5 (production) with PHP3 latest CVS and Apache 1.3.3. To reproduce the crash:
- run a script with Ora_Plogon
- stop oracle
- reload the script, apache core dumps.
Here is the dump:

I tried to narrow down the problem and wrote a small OCI programm to reproduce the problem, but it works fine. The programm connects to Oracle, stops (so you can shut down oracle). Then it tries to open a new cursor, it fails but it does not core dump.
