#31508 [WFx]: Apache 1.3.33 endless loop in _int_malloc()

ID: 31508 User updated by: yml at dtlink dot com Reported By: yml at dtlink dot com Status: Wont fix Bug Type: Apache related Operating System: Linux (RedHat 9) PHP Version: 4CVS-2005-01-13 New Comment: Maybe we are miscommunicating. This is not an infinite recursion problem. As you can see in the bug reports below, if I compile PHP with --enable-debug it works like a champ (i.e. no spinning) and clearly lists PHP /INTERNAL/ buffer overruns in the debug log. This is not an endless recursion problem. It is most likely a symbol table or stack management bug. At most I might have 20 levels of recursion when I parse XML documents but no more. As I've mentioned a few times I believe it may be similar or even related to a 100% reproducible PHP 5.0 bug that I have a test script for. Previous Comments: ------------------------------------------------------------------------ [2005-01-21 09:15:08] derick@php.net It can do that, but not infinitive recursion. The limit is about 2500 levels of function calls deep, but that may variate quite some depending on your situation. ------------------------------------------------------------------------ [2005-01-21 02:17:50] yml at dtlink dot com Ummm. You're not really saying that PHP can't do recursion, are you? That would be ludicrous. ------------------------------------------------------------------------ [2005-01-21 01:54:29] iliaa@php.net What you are experiencing is a stack smash caused by recurssion. This is unlikely to ever be fixed and is a good example of why not to use recursive functions. ------------------------------------------------------------------------ [2005-01-21 00:51:17] yml at dtlink dot com yes, I make alot of use of recursion. It's a system that constructs trees of objects based on an XML source file. I do a tremendous amount of object reference passing as well. The first version was built in 2001 and it's been growing since. I've run into several PHP symbol table corruption bugs since that time; most I haven't bothered to report since they're so difficult to reproduce. PHP versions since 4.3.4 have been /much/ more stable; until this bug which seems to be caused by a particular combination of object trees. ------------------------------------------------------------------------ [2005-01-21 00:40:47] iliaa@php.net Do you have recursive function calls in your script? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
