#34786 [NEW]: 2 @ results in change to error_reporting() to random value

From: cellog@php.net Operating system: linux (gentoo) PHP version: 5CVS-2005-10-08 (CVS) PHP Bug Type: Scripting Engine problem Bug description: 2 @ results in change to error_reporting() to random value Description: ------------ This is a critical bug in PHP 5.1 (PHP_5_1) latest CVS. running "make install-pear" results in all kinds of E_STRICT warnings. This is in spite of an explicit -derror_reporting=E_ALL I traced the problem using var_dump(error_reporting()); peppered throughout the source of install-pear.phar to a single line located in cvs at pear-core/Archive/Tar.php on line 706: @fseek($this->_file, @ftell($this->_file)+($p_len*512)); removing the second @ in front of ftell() fixes the problem. Reproduce code: --------------- make install-pear.phar use http://pear.php.net/~greg/install-pear.phar for a debug .phar that has inserted a few var_dump(error_reporting()); around the offending line. int(2047) is E_ALL, and after the line, there are 2 var_dump(error_reporting()) that spit out random integers, ranging from 10 to numbers like 14803908 to -14378917. A valgrind trace is at: http://pear.php.net/~greg/pearcrash.txt Expected result: ---------------- works with no warnings Actual result: -------------- install works sometimes, but there are lots of E_STRICT warnings. -- Edit bug report at http://bugs.php.net/?id=34786&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=34786&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=34786&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=34786&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=34786&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=34786&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=34786&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=34786&r=needscript Try newer version: http://bugs.php.net/fix.php?id=34786&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=34786&r=support Expected behavior: http://bugs.php.net/fix.php?id=34786&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=34786&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=34786&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=34786&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=34786&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=34786&r=dst IIS Stability: http://bugs.php.net/fix.php?id=34786&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=34786&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=34786&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=34786&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=34786&r=mysqlcfg
