To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If the script requires a database to demonstrate the issue, please make sure it creates all necessary tables, stored procedures etc. Please avoid embedding huge scripts into the report. ------------------------------------------------------------------------ [2016-11-02 04:50:14] yywangzheng at 126 dot com Description: ------------ #0 zend_destroy_property_info (property_info=0x0) at /src/php-5.6.27/ext/opcache/zend_accelerator_util_funcs.c:219 No locals. #1 0x00000000008543b8 in zend_hash_destroy (ht=0x7f640625d750) at /src/php-5.6.27/Zend/zend_hash.c:548 p = 0x0 q = 0x7f640625dfd8 #2 0x000000000083a5b6 in destroy_zend_class (pce=<optimized out>) at /src/php-5.6.27/Zend/zend_opcode.c:303 ce = 0x7f640625d6e0 #3 0x0000000000852e16 in i_zend_hash_bucket_delete (p=0x552fae0, ht=0x1f15c50) at /src/php-5.6.27/Zend/zend_hash.c:182 No locals. #4 zend_hash_bucket_delete (ht=ht@entry=0x1f15c50, p=p@entry=0x552fae0) at /src/php-5.6.27/Zend/zend_hash.c:192 No locals. #5 0x00000000008548ea in zend_hash_reverse_apply (ht=0x1f15c50, apply_func=apply_func@entry=0x835a30 <clean_non_persistent_class>) at /src/php-5.6.27/Zend/zend_hash.c:733 result = 1 p_last = 0x552fa90 p = 0x552fae0 #6 0x00000000008361b3 in shutdown_executor () ---Type <return> to continue, or q <return> to quit--- at /src/php-5.6.27/Zend/zend_execute_API.c:300 __orig_bailout = 0x7fff48c30dd0 __bailout = {{__jmpbuf = {18548672, 2408040186032662389, 0, 140734414147329, 0, 140067576603728, -2407874094099355787, 2408040160359982965}, __mask_was_saved = 0, __saved_mask = { __val = {2408038309018052469, 16038869976030904320, 2408038405528463221, 36418072, 38, 36532536, 36520632, 36532584, 36520632, 0, 1, 18547152, 18548408, 140734414147329, 8672014, 18548320}}}} #7 0x0000000000846732 in zend_deactivate () at /src/php-5.6.27/Zend/zend.c:960 No locals. #8 0x00000000007e51b1 in php_request_shutdown (dummy=dummy@entry=0x0) at /src/php-5.6.27/main/main.c:1899 report_memleaks = 1 '\001' #9 0x0000000000441928 in main (argc=<optimized out>, argv=<optimized out>) at /src/php-5.6.27/sapi/fpm/fpm/fpm_main.c:2017 primary_script = <optimized out> __orig_bailout = 0x0 __bailout = {{__jmpbuf = {0, -2407874094905710731, 4, 140734414147444, 4294967295, 0, -2407874093971429515, 2408038538697484149}, __mask_was_saved = 0, __saved_mask = {__val = { 0 <repeats 16 times>}}}} exit_status = 0 ---Type <return> to continue, or q <return> to quit--- c = <optimized out> use_extended_info = 0 file_handle = {type = ZEND_HANDLE_FILENAME, filename = 0x7f640625f458 "H\364%\006d\177", opened_path = 0x0, handle = {fd = 103366168, fp = 0x7f6406293e18, stream = { handle = 0x7f6406293e18, isatty = 0, mmap = {len = 138, pos = 0, map = 0x0, buf = 0x7f64062bf000 <Address 0x7f64062bf000 out of bounds>, old_handle = 0x0, old_closer = 0x0}, reader = 0x7fc850 <_php_stream_read>, fsizer = 0x7e2bc0 <php_zend_stream_fsizer>, closer = 0x7e2ba0 <php_zend_stream_mmap_closer>}}, free_filename = 0 '\000'} orig_optind = 1 orig_optarg = 0x0 ini_entries_len = <optimized out> max_requests = 0 requests = 275 fcgi_fd = <optimized out> request = {listen_socket = 0, fd = 4, id = 1, keep = 0, closed = 0, in_len = 0, in_pad = 0, out_hdr = 0x7fff48c30fa0, out_pos = 0x7fff48c3107e "MT\r\nCache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0\r\nPragma: no-cache\r\nContent-type: tex---Type <return> to continue, or q <return> to quit--- t/html; charset=UTF-8\r\n\r\n[]", out_buf = "\001\006\000\001\001g\001\000Status: 500 Internal Server Error\r\nExpires: Thu, 19 Nov 1981 08:52:00 GMT\r\nCache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0\r\nPragma: no-cache\r\nContent-type: text/h"..., reserved = '\000' <repeats 15 times>, env = 0x7f640625e040} fpm_config = 0x7fff48c34f74 "" fpm_prefix = 0x0 fpm_pid = 0x0 test_conf = 0 force_daemon = 0 force_stderr = 0 php_information = 0 php_allow_to_run_as_root = 0 __func__ = "main" ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=73440&edit=1
