From: [EMAIL PROTECTED] Operating system: Mac OS X 10.4 PHP version: 5CVS-2005-10-07 (snap) PHP Bug Type: PDO related Bug description: (DBLIB) Calling PDO::errorInfo causes SIGSEGV if no errors have occured
Description: ------------ Calling the PDO:errorInfo() after successful query execution might seem a little useless but it really shouldn't crash the process. I tracked down the problem with valgrind (on a debian box) and I'm pasting the partial output here: ==2622== Process terminating with default action of signal 11 (SIGSEGV) ==2622== Access not within mapped region at address 0x0 ==2622== at 0x1B9057F8: strlen (mac_replace_strmem.c:189) ==2622== by 0x82A11DA: add_next_index_string (zend_API.c:1040) ==2622== by 0x81556A3: dblib_fetch_error (dblib_driver.c:64) ==2622== by 0x82C1FB5: zend_do_fcall_common_helper_SPEC (zend_vm_execute.h:184) ==2622== by 0x82C17D8: execute (zend_vm_execute.h:87) ==2622== by 0x82A02CB: zend_execute_scripts (zend.c:1078) ==2622== by 0x82689BA: php_execute_script (main.c:1672) ==2622== by 0x83291C9: main (php_cli.c:1039) I'm not very good with C but I was able to alter the behavior to be the same (I believe) as with PgSQL driver with the following patch: --- dblib_driver.c.old 2005-10-07 11:45:24.000000000 +0300 +++ dblib_driver.c 2005-10-07 11:23:04.000000000 +0300 @@ -54,6 +54,10 @@ msg = einfo->dberrstr; } + if (einfo->dberr == 0) { + return 1; + } + spprintf(&message, 0, "%s [%d] (severity %d) [%s]", msg, einfo->dberr, einfo->severity, stmt ? stmt->active_query_string : ""); Reproduce code: --------------- <?php $pdo = new PDO(...); var_dump($pdo->errorInfo()); ?> Expected result: ---------------- array(1) { [0]=> string(0) "" } Actual result: -------------- zsh: bus error /usr/local/bin/php dblib.php -- Edit bug report at http://bugs.php.net/?id=34777&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=34777&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=34777&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=34777&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=34777&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=34777&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=34777&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=34777&r=needscript Try newer version: http://bugs.php.net/fix.php?id=34777&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=34777&r=support Expected behavior: http://bugs.php.net/fix.php?id=34777&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=34777&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=34777&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=34777&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=34777&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=34777&r=dst IIS Stability: http://bugs.php.net/fix.php?id=34777&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=34777&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=34777&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=34777&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=34777&r=mysqlcfg
