           Summary: -fcatch-undefined-behaviour doesn't catch missing
                    return values
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: C++

-fcatch-undefined-behaviour doesn't catch functions which fail to return a

int foo() {}

Calling foo() when compiled with -fcatch-undefined-behaviour should cause an

I believe hooking an abort() (or other function) onto the end of every method
when -fcatch-undefined-behaviour is used would catch such cases.
