If this happens also with soon to be released PHP 4.0.5, reopen this bug report with a short example script that can be used to reproduce this. --Jani Previous Comments: --------------------------------------------------------------------------- [2001-03-08 06:40:50] stas@php.net Please provide a short code reproducing the problem. --------------------------------------------------------------------------- [2001-02-26 16:34:15] mailling@bigfoot.com This problem seems to be related to the bug 9407 also. I am not sure it is due to the garbage collector. I ran it as a CGI or with ISAPI filter, I increased the amount of memeory a thread could take until 13Mb, with Linux also. I destroyed the process... I think it is due to a buffer overflow somewhere when a reference is built, or something like that. Good luck --------------------------------------------------------------------------- [2001-02-26 05:18:27] mailling@bigfoot.com I got in trouble with reference. Issues with Linux, Mandrake 7.2 and Windows 2000 with PHP 4.04pl1, php 4.0.3 php 4.0.1pl2 I am unable to give small script, the problem seems to appear only on big script, some refences seems to be messed up. What I did. I used MySql to query a system. When I check the result of a query, I got a resource ID But sometimes, the resource ID is a big number, ie 18739485 I belived the problem came from MySql, but I used ODBC to find a turn around, with the same problem. The worst is the such a resource is working well after for the next_record statement. Then, I realize a dump of a big variable, that contains references of objects, of arrays... And one of this variable inside is at the beginning a number, and becomes a reference to another object. I checked the code, and the variable is written only once. Something else, I write to the screen a string using printf() or echo sprintf(), and I find this string in the big variable. Worst, I notice some strange characters in this object (with ascii code >127) It seems that in some condition, the memory manager doesn't work well. With my code, PHP hangs on while it is trying to print a resource ID variable (on Unix or PHP). I can send you my code if you are interested in. For a core file, I didn't compile PHP- Linux with the debug option. Do you know how I can do the same thing with Windows? Hope that helps --------------------------------------------------------------------------- ATTENTION! Do NOT reply to this email!
