TYPO3 Core

The proposed and merged solution of #95066 has some undetected flaws:

• array unpacking fails if the array is associative (happens with SU mode, see https://github.com/TYPO3/typo3/blob/master/typo3/sysext/core/Classes/Error/ErrorHandler.php#L254)
• assumes all required arguments for sprintf() are available

Since both cases cannot be solved in a clean way it's better to revert the original patch and fix only the original issue.
