Bug #54007 [NEW]: odbc seg faults with null data returned from DB2

From: Operating system: Linux PHP version: 5.3.5 Package: ODBC related Bug Type: Bug 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. -- Edit bug report at http://bugs.php.net/bug.php?id=54007&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=54007&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=54007&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=54007&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=54007&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=54007&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=54007&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=54007&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=54007&r=needscript Try newer version: http://bugs.php.net/fix.php?id=54007&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=54007&r=support Expected behavior: http://bugs.php.net/fix.php?id=54007&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=54007&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=54007&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=54007&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=54007&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=54007&r=dst IIS Stability: http://bugs.php.net/fix.php?id=54007&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=54007&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=54007&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=54007&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=54007&r=mysqlcfg
