Updating from 7.4 to 7.7 we fell into an infinite loop before before update could complete. After searching the fora, it became clear that the issue was related to #1232346: easy to trigger infinite recursion in hook_menu() and hook_theme().
Looking at our backtrace, this module has a call to the l() function in the hook_menu() implementation, this coupled with a menu_get_item() call in custom search's hook_theme() caused the infinite loop. The custom search issue is #1235878: Infinite recursion in D7.

ronan commentedI'm not seeing the l() function you're referring to so I think this must have been fixed. Reopen if I'm missing something obvious.
