TYPO3 Core

Situation:
When having content elements of type "menu/sitemap" and using the subtype "Menu of these pages" then tslib_menu parses the values of config special.value with tslib_content.

Problem:
tslib_menu and tslib_Xmenu calls stdwrap on $GLOBALS['TSFE']->cObj instead of $this->parent_cObj which is not necessarily the same. tslib_content is not a singleton. $GLOBALS['TSFE']->cObj->data holds the data of the current page, whereas $this->parent_cObj->data holds the data of the calling content element or page

Solution:
Replace every occurence of $GLOBALS['TSFE']->cObj with $this->parent_cObj.
Attached Patch fixes the Problem.
