Bug #55753 [Fbk]: Sporadic crashes

Edit report at https://bugs.php.net/bug.php?id=55753&edit=1 ID: 55753 Updated by: pajoye@php.net Reported by: dado at burza dot hr Summary: Sporadic crashes Status: Feedback Type: Bug Package: Reproducible crash Operating System: Fedora 14 i686 PHP Version: 5.3.8 Block user comment: N Private report: N New Comment: not really, best would be to be using our src directly. You don't have to install PHP, it can be done using a local install in your home. If you can't do it, I would suggest to report the problem to fedora directly but without some kind of reproduce steps, there is little chance to get a fix. Previous Comments: ------------------------------------------------------------------------ [2011-09-21 09:10:14] dado at burza dot hr If I recompile the RPM having disabled all the patches, does that count? ------------------------------------------------------------------------ [2011-09-21 09:02:54] pajoye@php.net Please try using a plain vanilla php (from php.net) ------------------------------------------------------------------------ [2011-09-21 08:58:44] dado at burza dot hr Description: ------------ Using PHP 5.3.8-1.fc14 and 2.2.17-1.fc14 and having crashes on random URLs (cannot isolate the problem), but repeatable. Also having this issue (same URLs) on my live deployment of the app which runs PHP 5.2.
