            Bug ID: 25013
           Summary: [MS] #pragma vtordisp inside functions is not allowed
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: Frontend
          Assignee: unassignedclangbugs at nondot.org

    Classification: Unclassified

Clang fails to compile the following test, while MSVC compiles it without any
diagnostics:

$ cat 1.cpp

struct A {
  virtual ~A() {};
  virtual void foo() {};
  int a;
};

template <class T> struct B : virtual A {
  virtual ~B() {};
  virtual void bar() {};
  int b;
};

int main() {
  #pragma vtordisp(push, 2)
  B<int> obj;
  #pragma vtordisp(pop)
  return 0;
}


$ clang 1.cpp

1.cpp:14:11: error: expected expression
  #pragma vtordisp(push, 2)
          ^
1.cpp:16:11: error: expected expression
  #pragma vtordisp(pop)
          ^
2 errors generated.
