PHP 4.0 Bug #8392 Updated: crash with --enable-debug, backtrace sourcefile

ID: 8392 User Update by: mog@linux.nu Old-Status: Feedback Status: Open Bug Type: Reproduceable crash Description: crash with --enable-debug, backtrace sourcefile Hello. I'm sorry i haven't been able to reproduce this for a long time. I think this bug is dependend on certain db structure and code of other files included from the main file. And the new code doesn't use =& even though it doesn't crash when using it. Might be because the db was cleared and refilled. Anyway thanks for the (little late) feedback. - Mog Previous Comments: --------------------------------------------------------------------------- [2001-03-16 20:29:29] sniper@php.net Does this happen with latest CVS snapshot from http://snaps.php.net/ ?? --Jani --------------------------------------------------------------------------- [2000-12-23 21:44:21] mog@linux.nu hi agin if i use: $PHORUM_ROWS[$row["message_id"]] = $PHORUM_ROWS_UNSORTED[$key]; instead of: $PHORUM_ROWS[$row["message_id"]] =& $PHORUM_ROWS_UNSORTED[$key]; the crash doesn't occur, so apparantly it has to do with variable references and arrays or something thanks, keep up the good work! // Morgan --------------------------------------------------------------------------- [2000-12-23 21:32:21] mog@linux.nu for some reason it just crashes the distro is a standard redhat 7 with compiled php configured with './configure' '--with-gd' '--with-mysql' '--with-xml' '--with-apxs' --enable-debug too, but phpinfo() apparantly didn't list it the php file that crashes is available at: http://hem.netlink.se/~sft3905/list.php phpinfo(); output is available at: http://hem.netlink.se/~sft3905/phpinfo.html backtrace: (gdb) r -X -D HAVE_PHP4 Starting program: /usr/sbin/httpd -X -D HAVE_PHP4 Program received signal SIGSEGV, Segmentation fault. 0x402d8f71 in _efree (ptr=0x8125184) at zend_alloc.c:232 232 REMOVE_POINTER_FROM_LIST(p); (gdb) bt #0 0x402d8f71 in _efree (ptr=0x8125184) at zend_alloc.c:232 #1 0x402f0591 in _zval_dtor (zvalue=0x81237e4) at zend_variables.c:62 #2 0x402e8afe in zend_assign_to_variable (result=0x80f04ec, op1=0x80f04fc, op2=0x80f050c, value=0x80ecbbc, type=4, Ts=0xbfffb230) at ./zend_execute.c:357 #3 0x402e2525 in execute (op_array=0x80f2ee0) at ./zend_execute.c:1261 #4 0x402e375a in execute (op_array=0x8121ec4) at ./zend_execute.c:1559 #5 0x402e5d1d in execute (op_array=0x80e80a4) at ./zend_execute.c:2063 #6 0x402f18c1 in zend_execute_scripts (type=8, file_count=3) at zend.c:729 #7 0x40302aaf in php_execute_script (primary_file=0xbffff860) at main.c:1221 #8 0x402ff3e2 in apache_php_module_main (r=0x80e1c0c, display_source_mode=0) at sapi_apache.c:89 #9 0x402ffcf5 in send_php (r=0x80e1c0c, display_source_mode=0, filename=0x0) at mod_php4.c:506 #10 0x402ffd2a in send_parsed_php (r=0x80e1c0c) at mod_php4.c:517 #11 0x80538b9 in ap_invoke_handler () #12 0x80638d2 in ap_some_auth_required () #13 0x806393f in ap_process_request () #14 0x805cf37 in ap_child_terminate () #15 0x805d0bf in ap_child_terminate () #16 0x805d1d4 in ap_child_terminate () #17 0x805d6ff in ap_child_terminate () #18 0x805de38 in main () ---Type <return> to continue, or q <return> to quit--- #19 0x40145a7c in __libc_start_main (main=0x805db00 <main>, argc=4, ubp_av=0xbffffaf4, init=0x804f1d0 <_init>, fini=0x807e98c <_fini>, rtld_fini=0x4000d684 <_dl_fini>, stack_end=0xbffffaec) at ../sysdeps/generic/libc-start.c:111 thanks for your help! - Mog --------------------------------------------------------------------------- Full Bug description available at: http://bugs.php.net/?id=8392
