Bug #65932 [NEW]: 5.5 causes all PHP scripts to return 500 errors

From: php dot net at it-mate dot co dot uk Operating system: Server 2008 R2 PHP version: 5.5.5 Package: IIS related Bug Type: Bug Bug description:5.5 causes all PHP scripts to return 500 errors Description: ------------ Upgraded from 5.4.13 to the latest 5.5, but all PHP scripts fail with an HTTP 500 error (no details provided, regardless of the PHP and IIS debugging options). Not sure if this is due to my also using FastCGI (no way of testing at present as I've not got a spare test machine (they're all busy)). Dropped back to 5.4.21 for now. Any assistance would be appreciated. Test script: --------------- Latest phpBB and phpMyAdmin, along with all other PHP scripts (custom and third party) Expected result: ---------------- phpBB etc should be loading properly. Actual result: -------------- HTTP 500 error. -- Edit bug report at https://bugs.php.net/bug.php?id=65932&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=65932&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=65932&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=65932&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=65932&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=65932&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=65932&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=65932&r=needscript Try newer version: https://bugs.php.net/fix.php?id=65932&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=65932&r=support Expected behavior: https://bugs.php.net/fix.php?id=65932&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=65932&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=65932&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=65932&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=65932&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=65932&r=dst IIS Stability: https://bugs.php.net/fix.php?id=65932&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=65932&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=65932&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=65932&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=65932&r=mysqlcfg
