[Bug c++/21560] New: #pragma(1) doesn't work on the inner classes inside the temlated class

[yuri at tsoft dot com]

Example below prints 4, should be 1.
If #pragma pack() is removed it prints 1, also it prints 1 if the printing line
is also wrapped in pragmas.
If instead template stuff is removed at all it prints 1 correctly.

--example--

#include <iostream>
using namespace std;

template<typename C> struct Z {
#pragma pack(1)
  union Packed {
    struct {
     int dx:2;
     int dy:2;
    };
    unsigned char byte;
  };
#pragma pack()
};


main() {
  Z<int>::Packed x;
  cout << sizeof(x) << endl;
}

Confirmed, here is a compile time testcase instead of a runtime:
template<typename C> struct Z {
#pragma pack(1)
  union Packed {
    struct {
     int dx:2;
     int dy:2;
    };
    unsigned char byte;
  };
#pragma pack()
};

int f[sizeof(Z<int>::Packed)==1?1:-1];
