I have experienced the bug on SuSE Linux 9.3 (32bit) with Apache 2.0.55
in worker mode. PHP is also compiled as thread-safe. My reproduction
code:
<?php
file_get_contents('http://www.php.net/');
?>

PS: you've right, this problem only happend with threaded-webservers
(Apache2-worker)

Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read
http://bugs.php.net/bugs-generating-backtrace.php for *NIX and
http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32
Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.
We don't really support threaded webservers either...

The original assumption was bogus. The crash is independent of MySQL.
There were differences between my test and production systems that I did
not detect at first.
The problem is actually an issue with fopen().
Here is some code to reproduce:
<?php
$url="http://www.php.net";;
$xhtml = '';
if($filehandle = @fopen($url, 'rb')) {
$xhtml = fread($filehandle, 4096);
fclose($filehandle);
echo "$xhtml";
}
?>
This can be run either from the command line or as a webpage. In both
cases, PHP crashes.
Everthing works as expected when using the latest version of PHP5.

The latest version of PHP5 did not exhibit the problem.
Unfortunately, I have web sites that are not PHP5 compatible. The ones
that are compatible with PHP5 worked fine.
