I imagine this is the same basic problem as your previous question about 
Assert::IsNull, the difference between managed and native types.  
ExpectedException wants a managed type, i.e. a ref class or struct that 
gets created on the managed heap with gcnew.  std::bad_alloc is a native 
type, which gets created on the stack or on the unmanaged heap with 
normal C++ new, and you'll have to test for it the old fashioned way.  
In code:

[Test]
[ExpectedException(typeof(System::ApplicationException))]
void TestManagedException()
{
    throw gcnew System::ApplicationException();
}

[Test]
void TestNativeException()
{
    bool thrown = false;
    try { throw std::bad_alloc(); }
    catch( std::bad_alloc& ) { thrown = true; }
    Assert::IsTrue( thrown );
}
