Bug #13703 Updated: PHP allows function redefinition

ID: 13703 User updated by: yasuo_ohgaki@yahoo.com Reported By: yasuo_ohgaki@yahoo.com Status: Critical Bug Type: Scripting Engine problem Operating System: linux 2.4.4/glibc 2.2.2 PHP Version: 4.0CVS-2001-10-16 New Comment: Tested with CGI bin, I got 4.0.6: "Another A->test()" 4.0.4pl1: "Another A->test()" When I got both functions executed, memory is broken by some code. (I have no idea what's the cause of broken memory) [yohgaki@dev php-4.0.6]$ ./php ~/public_html/bugs/13703/test.php X-Powered-By: PHP/4.0.6 Content-type: text/html Another A->test() [yohgaki@dev php-4.0.6]$ cat config.nice #! /bin/sh # # Created by configure "./configure" \ "--without-mysql" \ "--without-pear" \ "--enable-debug" \ "$@" [yohgaki@dev php-4.0.6]$ [yohgaki@dev php-4.0.4pl1]$ ./php ~/public_html/bugs/13703/test.php Content-type: text/html; charset=EUC-JP Another A->test() [yohgaki@dev php-4.0.4pl1]$ Previous Comments: ------------------------------------------------------------------------ [2001-11-11 21:45:05] cnewbill@php.net Ditto with 4.0.6. -Chris ------------------------------------------------------------------------ [2001-11-11 21:30:16] sniper@php.net Marking as Critical for now. ------------------------------------------------------------------------ [2001-11-11 21:29:55] sniper@php.net I get "Another A->test()" with latest CVS. Anyone got older (4.0.6) to test this with? --Jani ------------------------------------------------------------------------ [2001-10-17 03:37:04] yasuo_ohgaki@yahoo.com I get only "A->test()" which is the first function definition. I'm not suprised. When I notice this bug in much complex scripts that have relatively complex class strucutre, PHP executed both functions that have the same name. (without error/warning) Does this bug's behaviour depend on configuration? If anyone need configure line, let me know. ------------------------------------------------------------------------ [2001-10-17 02:01:34] mfischer@php.net When reading your report I get the impression that the script outputs "A->test()\n" because you said "PHP executes first function test()". I get no redefinition error but on my system the second function is called so my output is "Another A->test()". So, two we have two different behaviours here or were your report not accurat? Anyway, it doesn't look good. - Markus ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
