PHP Bug Type: OCI8 related
Bug description: oci_connect crashes php when charset-parameter is given
Description:
------------
php crashes if the fourth/charset parameter is given to oc_connect or
oci_new_connect. Problem seems to be line 990 in oci8.c
Problem occurs also if ZendDebugger is not activated. Error occurs also in
older versions 5.0.5
Reproduce code:
---------------
<?php
$c=oci_new_connect("XXXXXXXX", "XXXXXXXX",
"XXXXXXX.XXXXXXX.XXX.XXXXXXXXXX", 'AMERICAN_AMERICA.WE8ISO8859P15');
Actual result:
--------------

line 990 in oci8.c is:
if (charset && *charset) {
smart_str_appends_ex(&hashed_details, charset,
1);
}
which then uses the macro from ./ext/standard/php_smart_str.h where the
memcopy is called
