Bug Type: IMAP related
Operating System: Linux (2.4.18)
PHP Version: 4.2.3
New Comment:
Your second bt shows that it's not an IMAP specific problem, which is
interesting that it manifests itself in IMAP only.
Can you reproduce this with non Apache2 as well (using the latest CVS
of course)? I know you probably hate me for asking this.

I deleted many html tags and php code.
Ctrl+F5(reload) gives good result or crash.
$ cat test.php
<?php
$mailbox = imap_open("{localhost:143}"."INBOX.test",
"[EMAIL PROTECTED]", "******");
$object = imap_fetchstructure($mailbox, 1);
$header = imap_header($mailbox, 1);
$from = $header->from[0]->personal;
if(!$from) $from = $header->$from[0]->mailbox;
$subject = htmlspecialchars(chop($header->Subject));
if(!$subject) $subject = "Null !!";
$to = $header->to[0]->personal;
if(!$to) $to = $header->to[0]->mailbox;
echo("Subject: $subject<br>");
echo("Date : " . $header->Date . "<br>");
echo("From : $from<br>");
echo("To : $to<br>");
imap_close($mailbox);
?>

The last error implies crash somewhere in the Apache 2 code. Does this
crash happen on any particular script, if so, could you please provide
the smallest possible version of such a script that can be used to
replicate the problem.

I tried above cvs version.
It worked but apache logs said,
[Wed Nov 06 00:44:50 2002] [notice] child pid 15305 exit signal
Segmentation fault (11)
[Wed Nov 06 00:44:55 2002] [notice] child pid 15371 exit signal
Segmentation fault (11)
[Wed Nov 06 00:44:58 2002] [notice] child pid 15401 exit signal
Segmentation fault (11)
and the back-trace here.
