This was reproduced on 3 separate servers, 2 Dell and 1 HP. The failure case CANNOT be reproduced on a machine with the same OS, Apache/php versions/config and code base that is running on a 32 bit base machine this was verified on 5 servers. In our failure case we are generating XML output on every request. It would seem like this is a issue when running 32 bit Win OS on 64 bit base machine. Unfortunately, I am unable to test this on 64 bit Windows 2003, however, I did retrograde a 64 bit OS a few months ago due to a very similar problem (not certain if it was exactly the same). Reproduce code: --------------- Not a developer. I will try and get our development team to create some code to reproduce, but they are very busy, so it may take some time. -- Edit bug report at http://bugs.php.net/?id=44645&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=44645&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=44645&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=44645&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=44645&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=44645&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=44645&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=44645&r=needscript Try newer version: http://bugs.php.net/fix.php?id=44645&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=44645&r=support Expected behavior: http://bugs.php.net/fix.php?id=44645&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=44645&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=44645&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=44645&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=44645&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=44645&r=dst IIS Stability: http://bugs.php.net/fix.php?id=44645&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=44645&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=44645&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=44645&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=44645&r=mysqlcfg
