test code

Clangs is unable to compile the following code:

void func(void)  throw (int) ;

struct Foo {
  void (*fp)(void) throw(int) ;
  void (&fr)(void) throw(int) ;
  Foo() :fp(func), fr(func) { }
};

Foo foo;

clang-arm-tip-x++ -c  func_ptr_exp.cpp 
func_ptr_exp.cpp:6:13: error: target exception specification is not superset of
source
  Foo() :fp(func), fr(func) { }
            ^
func_ptr_exp.cpp:6:23: error: target exception specification is not superset of
source
  Foo() :fp(func), fr(func) { }
                      ^
2 errors generated.


Without "throw (int)", it passes.
