Bug description:segfault in liclntsh.so when using shared oci8 extension
Description:
------------
use the latest php 5.3.5, tested in:
gcc 4.4.5, ubuntu 10.10 x86, oracle express;
gcc ???, asia linux 2(same as RHEL5?) x86, oracle 10g R2;
gcc ???, centos 4.5 x86, oracle 10g R1.
./configure --disable-all --disable-cgi --without-pear --with-
oci8=shared,$ORACLE_HOME
make
php.ini:
extension_dir = "./modules"
extension = oci8.so
oci8.privileged_connect = On
environment variable ORACLE_HOME and ORACLE_SID are both correct.
when using NULL as connection_string in oci_connect() to connect to
oracle:
sapi/cli/php -c php.ini -r "oci_internal_debug(TRUE);
var_dump(oci_connect('sys', 'sys', NULL, NULL, OCI_SYSDBA));"
it crashes:
OCI8 DEBUG: OCIHandleAlloc at

Segmentation fault
and the call stack shows that it crashes inside the libclntsh.so.
But if I provide a value for connection_string in oci_connect(), it works
fine,
and the call stack in the libclntsh.so is different.
And I try to build php using oci8 as a "static"
extension(--oci8=$ORACLE_HOME),
it also works fine when setting connection_string to NULL(this proves that
my
ORACLE_HOME and ORACLE_SID are correct).
And I test this in the previous three platforms, it acts the same. And I
also
try to use the latest instant client 10 and 11, the same results come out.
So I
believe that it can be easily reproduced in most or all platforms.
So is it the bug of php or oracle's client library???
