ID: 7686 User Update by: paul@rydell.com Status: Open Bug Type: Unknown/Other Function Description: Segmentation fault in complex pages when using sessions Sorry... forget that last long script. This will give you the seg fault much faster: <? header("Content-type: text/plain"); print "start.\n"; $x=array(); for ($j = 0; $j < 5000; $j++){ $x[]="This isa longsentence that needsto be wordwrappedThis isa longsentence that needsto be wordwrapped"; } for ($i = 0; $i < 5000; $i++){ $wrappedtext = wordwrap($x[i],5," ",1); } print "end.\n"; ?> Previous Comments: --------------------------------------------------------------------------- [2000-12-16 19:57:04] paul@rydell.com Okay. Here is a non-database script that can still cause the seg fault. It will not happen every time... you might have to reload a bunch of times to get it to happen or better yet use ./ab -n 5000 -c 10 http://localhost/crash.php3 to get some seg. faults. ------ <? header("Content-type: text/plain"); print "start.n"; $x=array(); $x[]="Collecting Hawaiiana, antiques, toys, &amp; other collectibles in Hawaii.
