Description: ------------ A segfault has existed in PHP since at least 5.2.17 when using ODBC with SQL Server Native Client driver. Selecting NULL values in a computed expression causes the segfault. I created a patch for this over a year ago and submitted the pull request here: https://github.com/php/php-src/pull/193 The pull request has not been accepted, so the segfault still exists even in 5.5.0beta2. Test script: --------------- <?php $conn = odbc_connect('Driver=SQL Server Native Client 11.0;server=xxx;uid=xxx;pwd=xxx;Database=xxx','',''); $query = odbc_exec($conn, 'select null'); $segfault = odbc_fetch_array($query); // segfault Expected result: ---------------- odbc_fetch_array to return a result rather than segfault. Actual result: -------------- segfault. -- Edit bug report at https://bugs.php.net/bug.php?id=64611&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=64611&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=64611&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=64611&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=64611&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=64611&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=64611&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=64611&r=needscript Try newer version: https://bugs.php.net/fix.php?id=64611&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=64611&r=support Expected behavior: https://bugs.php.net/fix.php?id=64611&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=64611&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=64611&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=64611&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=64611&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=64611&r=dst IIS Stability: https://bugs.php.net/fix.php?id=64611&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=64611&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=64611&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=64611&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=64611&r=mysqlcfg
