Description: Apache dumps core during mysql_fetch_array
It took me some time to find out, that this actually
is a bug in date(). Try the following script and have
a look at the H:i:s part of the second date:
------------------------snip-----------
<html><body><pre><?
flush();if (empty($max)) { $max=1000; }
for ($i=0;$i<$max;$i++) {
echo date("d.m.Y, H:i:s",time())." and now with r: ";
echo date("r \o\o\o\p\s>>>>> H:i:s",time())."\n";
flush();
}
?></pre></body></html>
------------------------snap------------
(the core dumps only occurred together with mysql,)

Apache 1.3.19 dumps core during mysql_fetch_array. The exact point
where this happens seems to be dependent on the number off string
concatenations during the while loop. This happens with mysql versions
3.23.22-beta, 3.23.32, 3.23.36.
