The code compiled fine w/ -Wall -Wextra -Werror w/ 4.6 and 4.7.Note that if the target architecture is a microcontroller, an endless loop can be a legitimate way to finish / abort the program.
But not an infinite recursion! And an endless loop is such a rare case that it deserves a warning, it's a false positive in this case, so what?
