Hello all, I was told this might be a better list to ask this question... I was experimenting with the imap_* library functions trying to see if I could get a PHP script to access a folder on our IMAP server and I ran into a problem. 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. Here is the code I was trying to run: <?php $mailbox = '{mail.hddbroker.com:143}INBOX'; $username = 'xxx'; $password = 'yyy'; $mbox = imap_open($mailbox, $username, $password); imap_close($mbox); ?> and on the CLI it produced the output: Segmentation fault (core dumped) I configured my PHP installation with --enable-debug and using the core dump, I got 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 It doesn't mean too much to me but I thought someone might be able to understand it. Here is some additional details that might be needed: PHP Version: PHP 5.2.0 (cli) (built: Nov 3 2006 06:07:03) OS: CentOS 4.4 i386 RPM packages installed: - openssl-0.9.7a-43.14 - openssl-devel-0.9.7a-43.14 - libc-client-2002e-14 - libc-client-devel-2002e-14 There was a bug opened that has the same segmentation problem but the scenario seems to be different including using a different version of PHP. PHP Bug #39726 (http://bugs.php.net/bug.php?id=39726) If there are any other details I can provide or if someone could point my in another direction that would help, I would really appreciate it. Thank you.
