This bug looks similar to #1931, but...

I'm running RedHat V6.0 on an AlphaServer DS10.
Packages: Apache 1.3.9, MySQL 3.22.27 and PHP 3.0.12
I have a similar configuration on a ProLiant 1850R which works fine.

1) Apache+MySQL+PHP module -- fopen on a URL fails with
"Invalid URL".  

2) I rebuild PHP as a standalone program and uncommented
some of debug code in url.c and found that url_parse() 
was failing after the second extended regexp.

3) Then rebuilt PHP as a standalong program using --with-system-regexp and then the code worked.  

4) HOWEVER, when I rebuilt PHP3 as an apache module --with-system-regexp, the code still fails, but with this in
the error log:

FATAL:  emalloc():  Unable to allocate 4294967293 bytes 

I can't get apache to leave a core file.  If httpd
is run from gdb, it simply dies with "Program exited with code 01." and bt says "No stack."

-------------------------------

The PHP3 code is the same one found in the manual:

<?

$fp = fopen("http://www.ispworks.com/", "r");

if (!$fp) {
	die("Can't open URL");
}

while ($buffer = fgets($fp, 4096)) {
  echo $buffer;
}
fclose($fp);
?>
