Previous Comments: --------------------------------------------------------------------------- [2001-03-21 21:55:17] max@the-triumvirate.net Under certain cercumstances imap_sort() will cause an apache child process to seg fault. Script: <?php $mbox = imap_open('{host.com/imap:143}INBOX', 'login', 'password', OP_READONLY); $results = imap_sort($mbox, 0, 0, SE_UID, 'UNSEEN'); var_dump($results); imap_close($mbox); ?> Run against a mailbox with 1 UNSEEN message, produces the correct output: array(1) { [0]=> int(953) } However running against a mailbox without any UNSEEN messages, apache dies. Attached is a gdb backtrace: (gdb) run ./httpd -X -DSSL Starting program: /usr/local/build/apache-build/apache-1.3.19/src/./httpd ./httpd -X -DSSL Program received signal SIGSEGV, Segmentation fault. 0x80c0aa7 in php_if_imap_sort (ht=5, return_value=0x83f1234, this_ptr=0x0, return_value_used=1) at php_imap.c:2750 2750 for (sl = slst; *sl; sl++) { (gdb) bt #0 0x80c0aa7 in php_if_imap_sort (ht=5, return_value=0x83f1234, this_ptr=0x0, return_value_used=1) at php_imap.c:2750 #1 0x8156bdf in execute (op_array=0x840c4cc) at ./zend_execute.c:1494 #2 0x812f25b in zend_execute_scripts (type=8, file_count=3) at zend.c:743 #3 0x80b37eb in php_execute_script (primary_file=0xbffff8b4) at main.c:1194 #4 0x813b97b in apache_php_module_main (r=0x834d98c, display_source_mode=0) at sapi_apache.c:89 #5 0x80b0ef6 in send_php () #6 0x80b0f2e in send_parsed_php () #7 0x81614a9 in ap_invoke_handler () #8 0x81763af in process_request_internal () #9 0x817641a in ap_process_request () #10 0x816d276 in child_main () #11 0x816d451 in make_child () #12 0x816d5cc in startup_children () #13 0x816dc3c in standalone_main () #14 0x816e48c in main () #15 0x400d49cb in __libc_start_main (main=0x816e0d4 <main>, argc=4, argv=0xbffffb44, init=0x80818c4 <_init>, fini=0x826dfa4 <_fini>, rtld_fini=0x4000ae60 <_dl_fini>, stack_end=0xbffffb3c) at ../sysdeps/generic/libc-start.c:92 This happens with both https and http as well as imaps and regular imap. other info: c-client 2000c --------------------------------------------------------------------------- ATTENTION!
