This should highlight memory corruption issues. ------------------------------------------------------------------------ [2006-04-09 14:10:44] joh at deworks dot net Just tested with the latest snapshot (php5.1-200604091030), and the problem still persists. ------------------------------------------------------------------------ [2006-04-09 07:52:21] wez@php.net Please try using this CVS snapshot: http://snaps.php.net/php5.1-latest.tar.gz For Windows: http://snaps.php.net/win32/php5.1-win32-latest.zip ------------------------------------------------------------------------ [2006-04-06 13:48:24] czw at home dot se Got the same error: PHP 5.1.2, MySQL 4.1.14. This error is NOT present in PHP 5.1.1. I would suggest downgrading. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
