--- Comment #4 from Jason Merrill <jason at gcc dot gnu.org> ---
The testcases in comments 2 and 3 are covered by bug 38172.  The original issue
is with unused inline functions, and affects C as well:

__attribute__((warn_unused_result)) int callme( ) { return 42; }

inline void foo()
{
  callme();
}
