Previous Comments: ------------------------------------------------------------------------ [2004-06-22 00:50:00] iliaa@php.net Thank you for this bug report. To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If possible, make the script source available online and provide an URL to it here. Try avoid embedding huge scripts into the report. ------------------------------------------------------------------------ [2004-06-19 18:42:54] tlawton at gmx dot de Description: ------------ Using the Win32 binaries from php.net, command line version. I'm doing some artificial intelligence work (I'm aware this isn't PHP's strongest point) with scripts that run for potentially hundreds of seconds, but don't use much memory. Intermittently I recieve this crash. It does not depend on the input data (ie immediately repeating the command with the same set of data may run to completion).

Code is essentially looped calculations on large arrays. I'll find somewhere to put the source later. Expected result: ---------------- Successful completion. Actual result: -------------- Crash as above. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=28844&edit=1
