#23483 [Opn->Bgs]: segfault when file uploading and using ADOdb

ID: 23483 User updated by: chip at cyan dot com Reported By: chip at cyan dot com -Status: Open +Status: Bogus Bug Type: Reproducible crash Operating System: Lunar-Linux (the edge) PHP Version: 4CVS-2003-05-04 (stable) New Comment: It looks like it was a bug inside a while loop deep inside some of my code. Still. Not cool that it was able to kill PHP like that. Previous Comments: ------------------------------------------------------------------------ [2003-05-04 18:45:35] chip at cyan dot com This is happening with a script that takes a http POST file upload. It then inserts the uploaded file into a SQL database using the ADOdb abstraction layer. This project is over 40,000 lines, so it is difficult to rip one page out of it. I try to get this into a reasonablely small packaged script later. Here is the script: http://php.red-illusions.dk/pasteit.php?id=191 (again, much of it won't make sense since much of the stuff is done outside this file.) This happens everytime using: Server version: Apache/2.0.45-dev Server built: Mar 8 2003 14:55:15 And PHP Snaps from: 2003-03-08 06:30 2003-05-04 21:30 (newest one)(and --enable-debug) After starting httpd in GDB using httpd -X -k start, and as soon as I visit this page and upload any file, I get my segfault. I do not get it by just visiting the page by itself, without any upload POSTs. Here is a full backtrace: (gdb) bt full #0 0x4021a92c in vfprintf () from /lib/libc.so.6 No symbol table info available. #1 0x4023741c in vsprintf () from /lib/libc.so.6 No symbol table info available. #2 0x40224d3d in sprintf () from /lib/libc.so.6 No symbol table info available. #3 0x40445a38 in _convert_to_string (op=0x82af4a0, __zend_filename=0x40498720 "/home/httpd/src/php4-STABLE-200305042130/Zend/zend_execute.c", __zend_lineno=2446) at /home/httpd/src/php4-STABLE-200305042130/Zend/zend_operators.c:453 lval = -1086320020 dval = 2.08422883873882e-269 tsrm_ls = (void ***) 0xbf40126c #4 0x4045e481 in execute (op_array=0x8339fe8, tsrm_ls=0x81d64e0) at /home/httpd/src/php4-STABLE-200305042130/Zend/zend_execute.c:2446 restored_error_reporting = {value = {lval = 137032864, dval = 1.7871824991067897e-262, str = {val = 0x82af4a0 'Z' <repeats 19 times>, "\204Ì\217*", len = 160858800}, ht = 0x82af4a0, obj = {ce = 0x82af4a0, properties = 0x99682b0}}, type = 1 '\001', is_ref = 23 '\027', refcount = 48960} execute_data = {opline = 0x833aa20, function_state = {function_symbol_table = 0x0, function = 0x8339fe8, reserved = {0x404511c5, 0x9968330, 0x40477f9c, 0x5}}, fbc = 0x0, ce = 0x0, object = {ptr = 0x0}, Ts = 0xbf4013a8, original_in_execution = 1 '\001', op_array = 0x8339fe8, prev_execute_data = 0xbf401e8c} #5 0x4045eecf in execute (op_array=0x82c26e0, tsrm_ls=0x81d64e0) at /home/httpd/src/php4-STABLE-200305042130/Zend/zend_execute.c:1650 execute_data = {opline = 0x8302054, function_state = {function_symbol_table = 0x99682b0, function = 0x8339fe8, reserved = {0x404511c5, 0x9968098, 0x40477f9c, 0x5}}, fbc = 0x8339fe8, ce = 0x0, object = {ptr = 0x99668f8}, Ts = 0xbf401818, original_in_execution = 1 '\001', op_array = 0x82c26e0, prev_execute_data = 0xbf403e9c} ...continued execute.... I noticed a simular backtrace in bug #20388 and they suggested trying to catch this in Xdebug ( http://xdebug.derickrethans.nl/ ) if i was entering a recursive function calling loop. Loading this made no difference for me.
