Bug description:odbc seg faults with null data returned from DB2
Description:
------------
This bug happens in many of the odbc functions that handle results from a
query,
but I'll point out one example:
The default case in php_odbc.c:
default:
if (result->values[field_ind].vallen == SQL_NULL_DATA) {
RETURN_NULL();
} else {
RETURN_STRINGL(result->values[field_ind].value, result-
>values[field_ind].vallen, 1);
}
break;
result->values[field_ind].vallen seems to be corrupted when fetching NULL
data
on a 64-bit system. Since it does not equal
SQL_NULL_DATA, the else clause is executed causing a seg fault because it
is
trying to handle a NULL case.
Test script:
---------------
I have no test script to show, because the only as400/db2 server I have
access to is behind a VPN at the moemnt.
