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)...

        100add4b 83e103           and     ecx,0x3

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 08:26 UTC] info at paradigmdirect dot com 
Crashes everytime from command line. 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');
}
?>

Please try using this CVS snapshot:

  http://snaps.php.net/php4-STABLE-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php4-win32-STABLE-latest.zip

Can't reproduce with latest stable snapshot under winxp.

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.

Please try using this CVS snapshot:

  http://snaps.php.net/php4-STABLE-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php4-win32-STABLE-latest.zip

Please try a newer snapshot; I fixed the probable cause of this bug a few minutes before your most recent comment; the snap containing that fix should be available now.

I tested the latest cvs version on about 100k urls last night and not one error! Closed. Thanks!
