The most obvious problematic cases are where control can't reach the end
of the function because of a call to a nonreturning function, but the
maintainer wants to avoid annotations specific to a particular compiler
(in this case, __attribute__((__noreturn__))) in their source code so the
compiler doesn't know that the function is nonreturning.
