When opening a IMAP stream to a POP3 server, and running a imap_headerinfo on a message, PHP gives a segmentation fault.

I found a few other bugs that looked similar to this one:

Tested on:

IMAP versions:

PHP configure:
'./configure' '--prefix=/usr' '--with-apxs=/usr/sbin/apxs' '--with-config-file-path=/etc/apache' '--enable-safe-mode' '--with-openssl' '--enable-bcmath' '--with-bz2' '--enable-calendar' '--enable-ctype' '--with-gdbm' '--with-db2' '--enable-dbase' '--enable-ftp' '--with-mysql=/usr/local/mysql' '--with-gd=/usr/local' '--with-jpeg-dir=/usr' '--with-png-dir=/usr/' '--with-xpm-dir=/usr/X11R6' '--with-zlib=/usr' '--with-ttf=/usr/X11R6/include/freetype' '--enable-xslt' '--with-xslt-sablot=/usr/local' '--with-expat-dir=/usr/local' '--with-dom=/usr/local' '--with-dom-xslt=/usr/local' '--with-dom-exslt=/usr/local' '--with-pgsql=/usr/local/pgsql' '--with-interbase=/opt/interbase' '--disable-magic-quotes' '--with-curl=/usr' '--with-imap=/usr/local/imap-2002d' '--enable-debug'

Reproduce code:
header('Content-type: text/plain');
$mbox = imap_open('{localhost:110/pop3}', 'user', 'password');
$numMsg = imap_num_msg($mbox);

for($i = 1; $i <= $numMsg; $i++)
    $header = imap_headerinfo($mbox, $i);

Expected result:
As an Apache module, nothing appears (Mozilla doesn't update the page, it just shows the previous non-error rendition of the page).

Command line:
$ php index.php
Segmentation fault (core dumped)

Actual result:
$ gdb /usr/bin/php core
// loads libraries

Can you print the value of tmp->personal

Can you print the contents of the tmp structure or possible make a text file with the complete message that causes the crash?
