Bug #15651 Updated: Output is broken

ID: 15651 Updated by: mfischer@php.net Reported By: pilots@farlep.net -Status: Open +Status: Closed Bug Type: Scripting Engine problem Operating System: Win2K-Server / UNIX PHP Version: 4.1.1 Previous Comments: ------------------------------------------------------------------------ [2002-06-06 21:35:35] pilots@farlep.net It seems this bug does not appear in 4.2.1. Checked on Linux/Apache. ------------------------------------------------------------------------ [2002-06-06 20:05:47] sniper@php.net reclassified. You should also try the latest release 4.2.1 (just in case someone already fixed this) ------------------------------------------------------------------------ [2002-02-23 07:27:54] pilots@farlep.net I've found a decision of problem: I simply need replase line if (is_array($argv[0])) $argv=&$argv[0]; to: if (is_array($argv[0])) $argv=$argv[0]; And I'll not lose any fuctionality features. So, crush appears when an array element assigns to the same array by reference. Althow this operation is not very often and very useful :-), it works correctly and w/o crush in 4.0.6 version, and I think this crush should be fixed though. ------------------------------------------------------------------------ [2002-02-23 06:46:36] pilots@farlep.net I made test using the advised method, and found that crush appears in one my simple function "call". A simple example goes below: <? // --------------------------------------\ // Apply specified function to arguments // if 2'nd argument is an array, its elements replace arguments // it's a way to apply function to arguments by their references // Examples: // list($c1)=call("intval",$a1); // list($c2,$c3)=call("htmlspecialchars",$b2,$b3); // call("htmlspecialchars",array(&$b2,&$b3)); // ------------------------------------\ function call() { if (func_num_args()<2) return false; $argv=func_get_args(); $func=array_shift($argv); error_log(__FILE__.'('.__LINE__.')'); // if (is_array($argv[0])) $argv=&$argv[0]; // Crush is here error_log(__FILE__.'('.__LINE__.')'); // reset($argv); while (list($k,$v)=each($argv)) $argv[$k]=$func($v); reset($argv); return $argv; } // ------------------------------------/ call("intval",1); // OK call("intval",array(1)); // Crush ?> Note: actually cutting line goes some earlier than that crush point, but, I think it's because some PHP bufferization, and is not important now. ------------------------------------------------------------------------ [2002-02-22 06:35:16] yohgaki@php.net Could you set up linux/freebsd box to reproduce this bug? And generate backtrace. (Or get exit code with gdb) You can write "error_log(__FILE__.'(.'__LINE__.')')" to locate to find ofending function/line also. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
