This happens for all tested data types, using named vs numbered bound parameters, and on every version of php tested (5.6, 7.2, 7.3). This happens regardless of what it is fetching. 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 this bug report at https://bugs.php.net/bug.php?id=79611&edit=1
