PHP 4.0 Bug #7670: PHP crashes when accessing IMAP mailbox

From: skarkkai@woods.iki.fi Operating system: Linux PHP version: 4.0.3pl1 PHP Bug Type: Reproduceable crash Bug description: PHP crashes when accessing IMAP mailbox When Courier IMAPd crashes while being accessed by IMP using PHP's IMAP functions, that causes also the Apache process to crash. The last IMAP messages before the crash are 00000005 SEARCH ALL UNSEEN * SEARCH 29 30 31 32 33 34 35 00000005 OK SEARCH done. 00000006 FETCH 29:35 (UID ENVELOPE BODY.PEEK[HEADER.FIELDS (Path Message-ID Newsgroups Followup-To References)] INTERNALDATE RFC822.SIZE FLAGS) Stack trace is obviously quite useless, as it is: #0 0x3a4c8d10 in ?? () #1 0xbf60b801 in ?? () #2 0xc8b604ff in ?? () #3 0x7e7fc391 in ?? () #4 0xc8b604ff in ?? () #5 0x7e710cf1 in ?? () #6 0xd029715b in ?? () #7 0xa1a1ee2f in ?? () #8 0x55e8be66 in ?? () This happens both with PHP 3.0.16 and 4.0.3pl1. Apache is 1.3.11. I compile PHP with ./configure --with-mysql=/usr --with-apxs=/usr/local/www/apache/bin/apxs --with-xml --enable-track-vars=yes --enable-bcmath=yes --enable-memory-limit=yes --with-imap --with-ldap --enable-sysvshm --enable-sysvsem --with-gdbm I can easily reproduce the crash by putting an offending email message into a Maildir that Courier reads. Any other information I should provide? -- Edit Bug report at: http://bugs.php.net/?id=7670&edit=1
