Bug Type: IMAP related
Operating System: GNU/Linux 2.4.9-34smp
PHP Version: 4.2.3
New Comment:
As this bug is not fixed in php4-STABLE (only in php4-LATEST) here is a
patch I made to correct this bug :
--- COPY START ---
[jonfray@localhost php-4.2.3]$ diff ext/imap/php_imap.c.old
ext/imap/php_imap.c
60a61
> #define PHP_IMAP_ADDRESS_SIZE_BUF 10
3592c3593
< int ret=0;
---
> int ret=0, num_ent=0;
3600a3602
> num_ent++;
3604c3606
< ret += (ret) ? MAILTMPLEN : 0;
---
> ret += (ret) ? num_ent*PHP_IMAP_ADDRESS_SIZE_BUF : 0;
--- COPY STOP ---
And it works !

This bug has been fixed in CVS.
In case this was a PHP problem, snapshots of the sources are packaged
every three hours; this change will be in the next snapshot. You can
grab the snapshot at http://snaps.php.net/.
In case this was a documentation problem, the fix will show up soon at
http://www.php.net/manual/.
In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites in short time.
Thank you for the report, and for helping us make PHP better.
The crash occured due to the old code not being able to handle emails
where there were more then 100 or so 'To:' headers.

If a mail has a very very long Header
(From field for example) Apache get killed
and this kind of entry is added to the logfile :
[Mon Oct 14 19:27:05 2002] [notice] child pid 29327 exit signal
Segmentation fault (11)
I know that the Header fields are normaly limited (1024 I think) in the
IMAP RFC but extra chars should be skiped (if any)
thanks
