#35837 [NEW]: Crash when using PDO::FETCH_LAZY

From: mfischer@php.net Operating system: Windows PHP version: 5CVS-2005-12-29 (snap) PHP Bug Type: PDO related Bug description: Crash when using PDO::FETCH_LAZY Description: ------------ PHP crashes at the end of the script when I use PDO::FETCH_LAZY. I've to say that from my testing (for some clever reason I started to use PDO::FETCH_LAZY right from the start and therefore have gone through many obscure crashes and exceptions) that I also saw the following problems with it: * it seems to consume memory and never releases it. I've got exception thrown from the Microsoft Access Driver about running out of memory. When I stopped using PDO::FETCH_LAZY the exception was never thrown again. * I got exception thrown about "invalid table ids" for now reasons which also went away when I stopped using PDO::FETCH_LAZY I was working with an Access Database (mdb file) but never fetching big data but it were about 1500 SQL statements sent. I've read report http://bugs.php.net/bug.php?id=35431 but I can confirm this for the current snapshot also. Reproduce code: --------------- $p = new PDO('odbc:driver={Microsoft Access Driver (*.mdb)};Dbq=beispieldatenbank.mdb'); $s = $p->query("SELECT COUNT(*) FROM ADDRESSES WHERE GUID = ''", PDO::FETCH_LAZY); $s->fetch(); Expected result: ---------------- Script should not crash. Actual result: -------------- Script crashes and Windows prompts me with a dialog to send a report to M$ -- Edit bug report at http://bugs.php.net/?id=35837&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=35837&r=trysnapshot44 Try a CVS snapshot (PHP 5.1): http://bugs.php.net/fix.php?id=35837&r=trysnapshot51 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=35837&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=35837&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=35837&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=35837&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=35837&r=needscript Try newer version: http://bugs.php.net/fix.php?id=35837&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=35837&r=support Expected behavior: http://bugs.php.net/fix.php?id=35837&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=35837&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=35837&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=35837&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=35837&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=35837&r=dst IIS Stability: http://bugs.php.net/fix.php?id=35837&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=35837&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=35837&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=35837&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=35837&r=mysqlcfg
