#41781 [NEW]: PHP loses the reference to the default parameter

From: skettler@php.net Operating system: Linux 2.6.20.2 / Debian Sarge PHP version: 5.2.3 PHP Bug Type: Scripting Engine problem Bug description: PHP loses the reference to the default parameter Description: ------------ When using a pass by reference parameter with a default value, the scripting engine does not always remember that reference. The script shows that ++$i; func($i); and func(++$i); are not equivalent at all times. When not using the default value and submitting an actual variable, both expressions are handled the same way. Reproduce code: --------------- See http://helplets.com/PHP/referencebug.txt Expected result: ---------------- 0123456 -------- 0123456 -------- 0123456 Actual result: -------------- 0123456 -------- 01234545 -------- 0123456 -- Edit bug report at http://bugs.php.net/?id=41781&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=41781&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=41781&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=41781&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=41781&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=41781&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=41781&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=41781&r=needscript Try newer version: http://bugs.php.net/fix.php?id=41781&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=41781&r=support Expected behavior: http://bugs.php.net/fix.php?id=41781&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=41781&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=41781&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=41781&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=41781&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=41781&r=dst IIS Stability: http://bugs.php.net/fix.php?id=41781&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=41781&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=41781&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=41781&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=41781&r=mysqlcfg
