#39875 [NEW]: imap_open causes a segmentation fault

From: richard at hddbroker dot com Operating system: CentOS 4.4 i386 PHP version: 5.2.0 PHP Bug Type: IMAP related Bug description: imap_open causes a segmentation fault Description: ------------ I was trying to get a simple script to work which simply opened a connection to the mail server and then closed it but when I ran the script it caused a segmentation fault on the imap_open line. Reproduce code: --------------- <?php $mailbox = '{mail.hddbroker.com:143}INBOX'; $username = 'xxx'; $password = 'yyy'; $mbox = imap_open($mailbox, $username, $password); imap_close($mbox); ?> If I run the script via the CLI version of PHP it prints "Segmentation fault (core dumped)". If I run the script via a web server, an empty page is returned. Expected result: ---------------- In this particular script I expected the imap_open function to return a resource object. Actual result: -------------- I configured my PHP with --enable-debug and followed the steps to get the following backtrace: #0 0x00144019 in SSL_SESSION_hash () from /lib/libssl.so.4 #1 0x001ca484 in lh_free () from /lib/libcrypto.so.4 #2 0x001ca5f3 in lh_delete () from /lib/libcrypto.so.4 #3 0x00148141 in SSL_CTX_get_timeout () from /lib/libssl.so.4 #4 0x001ca56e in lh_retrieve () from /lib/libcrypto.so.4 #5 0x001481f7 in SSL_CTX_flush_sessions () from /lib/libssl.so.4 #6 0x001441a3 in SSL_CTX_free () from /lib/libssl.so.4 #7 0x005185ac in ssl_close () from /usr/lib/libc-client.so.0 #8 0x0051851f in ssl_close () from /usr/lib/libc-client.so.0 #9 0x005176c3 in ssl_aopen () from /usr/lib/libc-client.so.0 #10 0x0054a697 in imap_open () from /usr/lib/libc-client.so.0 #11 0x00523a90 in mail_open () from /usr/lib/libc-client.so.0 #12 0x0814dcfc in zif_imap_open (ht=3, return_value=0xb7c8bc9c, return_value_ptr=0x0, this_ptr=0x0, return_value_used=1) at /usr/local/src/php-5.2.0/ext/imap/php_imap.c:780 #13 0x08332c92 in zend_do_fcall_common_helper_SPEC (execute_data=0xbfe372e0) at /usr/local/src/php-5.2.0/Zend/zend_vm_execute.h:200 #14 0x08332419 in execute (op_array=0xb7c8b68c) at /usr/local/src/php-5.2.0/Zend/zend_vm_execute.h:92 #15 0x0831aa9b in zend_execute_scripts (type=8, retval=0x0, file_count=3) at /usr/local/src/php-5.2.0/Zend/zend.c:1097 #16 0x082e4a51 in php_execute_script (primary_file=0xbfe397d0) at /usr/local/src/php-5.2.0/main/main.c:1758 #17 0x08393462 in main (argc=2, argv=0xbfe398a4) at /usr/local/src/php-5.2.0/sapi/cli/php_cli.c:1108 -- Edit bug report at http://bugs.php.net/?id=39875&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=39875&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=39875&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=39875&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=39875&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=39875&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=39875&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=39875&r=needscript Try newer version: http://bugs.php.net/fix.php?id=39875&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=39875&r=support Expected behavior: http://bugs.php.net/fix.php?id=39875&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=39875&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=39875&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=39875&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=39875&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=39875&r=dst IIS Stability: http://bugs.php.net/fix.php?id=39875&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=39875&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=39875&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=39875&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=39875&r=mysqlcfg
