[Bug c++/27577] New: Change "control reaches end of non-void function" to an error, when a complex type gets returned

["wfor at arcor dot de" <gcc-bugzilla at gcc dot gnu dot org>]

At least on x86 and x86_64 the following program crashes
------------8<--------------
#include <string>

std::string foo()
{
}

int main()
{
        foo();
}
------------8<--------------

When one compiles this snipplet with warnings turned on, then this warning
shows up:g++ -Wall m.c
m.c: In function `std::string foo()':
m.c:5: warning: control reaches end of non-void function


Although, a missing return type for a primitive type like int, float, ... is
sure not worth an error, not returning a complex type like std::string which
crashes the program should be treated as an error.

Yes, I am fully aware, that my snipplet is buggy, however an ignored warning
should not cause a crash in the program.
