[Bug c++/19400] New: vector keyword in typedef inside struct ignored

[leblanc at skycomputers dot com]

This program

 1  #include 
 2  #include 
 3
 4  struct s {
 5  typedef vector float vf;
 6  vf v1;
 7  vector float v2;
 8  } S;
 9
10  int main () {
11  printf ("sizeof(s::vf) is %d\n",sizeof(s::vf));
12  printf ("sizeof(S.v1) is %d\n",sizeof(S.v1));
13  printf ("sizeof(S.v2) is %d\n",sizeof(S.v2));
14  printf ("sizeof(S) is %d\n",sizeof(S));
15  return 0;
16  }

prints

sizeof(s::vf) is 4
sizeof(S.v1) is 4
sizeof(S.v2) is 16
sizeof(S) is 32

I would expect the 4-s to be 16-s.

The bug I reported in #19400, duplicating this one, is fixed in the compiler as 
of 1/12/04.  However, 
this variant remains busted:

 1  #include 
 2  #include 
 3
 4  template < typename Val > struct S {
 5  typedef vector Val vector_type;
 6  void pr_size() { printf ("size = %d\n", sizeof(vector_type)); }
 7  };  
 8
 9  int main()
10  {
11printf ("size = %d\n", sizeof(S < float >::vector_type));
12S x;
13x.pr_size();
14return 0;
15  }

because it prints

size = 4
size = 4

The program below prints 4-s instead of 16-s.

 1  #include 
 2  #include 
 3
 4  template < typename Val > struct S {
 5  typedef vector Val vector_type;
 6  void pr_size() { printf ("size = %d\n", sizeof(vector_type)); }
 7  };  
 8
 9  int main()
10  {
11printf ("size = %d\n", sizeof(S < float >::vector_type));
12S x;
13x.pr_size();
14return 0;
15  }
