#23380 [Fbk->Opn]: Seems to be an fopen bug.

ID: 23380 User updated by: info at paradigmdirect dot com Reported By: info at paradigmdirect dot com -Status: Feedback +Status: Open Bug Type: Reproducible crash Operating System: w2k sp3 PHP Version: 4.3.2RC1 New Comment: I tried the snapshot and it does indeed open the file I posted here but still fails when you put it in a loop and open random url's from a mysql db. It seems to be worse than the 4.3.2rc1 as far as how long it will run. Seems to fail after about 4 or 5 opens. I'll try to find a url that crashes it always.

The url is a 404 but usually fopen handles them. Not sure if the crash is always from a 404 either. I'll try to find out more. <? $url = 'http://www4.yahoo.com/Education/Universities/Venezuela'; $fp = fopen($url,'rb'); } ?> ------------------------------------------------------------------------ [2003-04-28 08:14:24] info at paradigmdirect dot com Refer to bug #22820. It has all the detailed information but has not been fixed and is closed. I can cut and paste it in here if you need me too. ------------------------------------------------------------------------ [2003-04-28 08:02:50] sniper@php.net Not enough information was provided for us to be able to handle this bug.

Thank you for your interest in PHP. ------------------------------------------------------------------------ [2003-04-28 08:01:23] info at paradigmdirect dot com I added this to closed bug #22820 also.... I have a bit of code that does the exact same thing as in 22820. It is unfortunately too big as Nick pointed out with his. The common thing is fopen on a url and a connection to mysql. The errors occur all over the place according to dr watson. Here are some examples: function: efree FAULT ->100b8fb4 8b4608 mov eax,[esi+0x8] ds:00a7d5c2=???????? ...another... function: zend_hash_index_update_or_next_insert FAULT ->100adc49 892cb1 mov [ecx+esi*4],ebp ds:0000000b=???????? ...another (whole)... function: zend_hash_rehash 100add42 c1e902 shr ecx,0x2 100add45 f3ab rep stosd es:00ce8c60=011931f0 100add47 8bce mov ecx,esi 100add49 33f6 xor esi,esi 100add4b 83e103 and ecx,0x3 100add4e f3aa rep stosb es:00ce8c60=f0 100add50 8b4214 mov eax,[edx+0x14] ds:01766eb2=???????? 100add53 3bc6 cmp eax,esi 100add55 7427 jz do_bind_function_or_class+0x2b2e (100b687e) 100add57 8b4a04 mov ecx,[edx+0x4] ds:01766eb2=????????
