            Bug ID: 18901
           Summary: function not returning declared value cause crash
           Product: clang
           Version: 3.4
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
          Assignee: unassignedclangbugs at nondot.org

I know of this bug which is pretty much the same:
http://llvm.org/bugs/show_bug.cgi?id=17375
It's been declared resolved invalid but really it is an issue.
Here is my code demonstrating the issue. Could not be shorter:

int func()
{
}
int main()
{
func();
return 0;
}

Crashes with illegal instruction when compiled with clang++
It passes with clang. (the file name I used was test.c with lowercase c)

I was bitten by this using Lua. This is code I do not write. If I use a library
that does not do return, I should not have my code crash.
I think this bug is fully alive and important and not "resolved invalid"
