Bug description: imap_mailboxmsginfo causes SIGBUS in Apache
Description:
------------
Apparently there seems to be some problems with imap_mailboxmsginfo(),
causing a SIGBUS error in Apache.
My configure-line is
./configure' \
'--with-apxs=/usr/local/apache/bin/apxs' \
'--enable-cli' \
'--with-zlib' \
'--with-bz2' \
'--with-dom' \
'--with-dom-xslt' \
'--with-dom-exslt' \
'--with-expat' \
'--enable-exif' \
'--enable-ftp' \
'--with-jpeg-dir=/usr/local' \
'--with-gd' \
'--with-pgsql' \
'--with-gettext' \
'--with-ldap' \
'--with-mcrypt' \
'--enable-pcntl' \
'--with-pdflib' \
'--enable-sockets' \
'--enable-wddx' \
'--with-openssl' \
'--with-curl' \
'--with-interbase' \
'--with-xmlrpc' \
'--with-yaz' \
'--enable-shmop' \
'--with-imap=/usr/local/imap-2000e' \
'--enable-debug' \
IMAP being imap-uw version 2000e. I've also tried imap-2002d, both of
which gave the same error.
I did read about mcrypt being one possible problem, so I updated that to
version 2.6.4_1 in the FreeBSD ports collection, but that didn't help
either.
Reproduce code:
---------------
<?php
if (($mbox = imap_open('{mail.server:110/pop3}', 'user', 'password')) ===
FALSE) {
imap_close($mbox);
var_dump(imap_errors());
}
$check = imap_mailboxmsginfo($mbox);
imap_close($mbox);
?>
Expected result:
----------------
Nothing happens when running the above code, except
Apache (1.2.27) crashing with a SIGBUS and a
[Sun Oct 19 18:41:40 2003] [notice] child pid 27550 exit signal Bus error
(10)
being left in the Apache error logs.
Actual result:
--------------
The GDB backtrace looks like this:
Program received signal SIGBUS, Bus error.
