Test script: --------------- <?php try { $conn = new PDO("odbc:<yourdatabaseDSN>"); } catch (PDOException $e) { print "Error!: " . $e->getMessage() . "\n"; die(); } /* Adjust the SQL statement below to your test environment. */ $stmt = $conn->prepare("CALL LIBRARY.GETDB(? , ?)"); $intvalue = 10; $strvalue = "abc"; $stmt->bindParam(1, $intvalue, PDO::PARAM_INT|PDO::PARAM_INPUT_OUTPUT, 4); $stmt->bindParam(2, $strvalue, PDO::PARAM_STR|PDO::PARAM_INPUT_OUTPUT, 100); print "before execute\n"; $res = $stmt->execute(); print "after execute\n"; var_dump($intvalue); var_dump($strvalue); ?> Expected result: ---------------- Proper execution and normal program exit Actual result: -------------- zend_mm_heap corrupted ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=67919&edit=1
