-Summary: misstyped opendir segfaults apache
Reported By: [EMAIL PROTECTED]
Status: Analyzed
Bug Type: Directory function related
Operating System: LInux 2.4.18
PHP Version: 4.1.2
New Comment:
it's not exclusive to opendir(). this blows up, too:
<?
$baz = fopen("/tmp/foo","w");
define("FOOBAR",$baz);
$foo=fopen("/tmp/bar", "w");
?>
(should you even be able to define() a resource? seems like a recipe
for trouble.)

Reproduced, there's something weird going on:

This probably doesn't matter much but.
Due to a faulty copy/paste on a script, i noticed that apache segfaults
on the following code:
<?
define("FOOBAR",opendir("/tmp/"));
$foo=opendir("/etc/");
?>
Obviously this code is incorrect, but still you might find usefull to
correct the segfault.
error.log:
[Sat May 11 02:32:51 2002] [notice] child pid 13397 exit signal
Segmentation fault (11)
(repeats)
