From: tom at advancedatatools dot com Operating system: CentOS PHP version: 7.2.31 Package: PDO ODBC Bug Type: Bug Bug description:PDO ODBC- Informix segfaults when fetching data using bound parameters Description: ------------ When doing a simple query using bound parameters php segfaults on the fetch line.

This is using Informix as the back end engine. Test script: --------------- $sth = $dbh->prepare("select item_num from items where item_num = ?"); $sth->bindParam(1,2); #Works $sth->execute(); #Segfaults for any type of fetch $row = $sth->fetch(PDO::FETCH_NUM); Expected result: ---------------- $row should return the record Actual result: -------------- Segmentation fault (core dumped) -- Edit bug report at https://bugs.php.net/bug.php?id=79611&edit=1 -- Fix committed: https://bugs.php.net/fix.php?id=79611&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=79611&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=79611&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=79611&r=needscript Try newer version: https://bugs.php.net/fix.php?id=79611&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=79611&r=support Expected behavior: https://bugs.php.net/fix.php?id=79611&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=79611&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=79611&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=79611&r=globals PHP version support discontinued: https://bugs.php.net/fix.php?id=79611&r=phptooold Daylight Savings: https://bugs.php.net/fix.php?id=79611&r=dst IIS Stability: https://bugs.php.net/fix.php?id=79611&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=79611&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=79611&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=79611&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=79611&r=mysqlcfg
