Previous Comments: ------------------------------------------------------------------------ [2005-12-29 11:56:36] mfischer@php.net 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 this bug report at http://bugs.php.net/?id=35837&edit=1
