Description:
------------
Using php 5.0.4, with the oci8 extension from CVS & the oci_ping code
activated in _oci_open_server, I have random segfaults on my production
servers.
Here is the back trace :
#0 0xb78f3779 in _oci_close_session (session=0x8382a20)

(gdb) print *session
$1 = {num = 137800016, persistent = 0 '\0', is_open = 253 'ý',
exclusive = 49 '1', thread = 8 '\b', sessions_list = 0x0, server =
0x0,
pSession = 0x0, pEnv = 0x0, charsetId = 0}
I'll try this patch in _oci_close_session :
if (!session) {
return;
}
+ if (!session->server) {
+ return;
+ }
oci_debug("START _oci_close_session: logging-off
sess=%d",session->num);
Reproduce code:
---------------
No reproducing code. The crashes are random & time/traffic dependant.
