Comment 0 for bug 662324

I'm using r162345 on x86 Fedora 13.

This test case comes from the gdb test suite.

struct A
{
  virtual ~A ();
  int a1;
};

A::~A()
{
  a1 = 800;
}

struct B : public A
{
  virtual ~B ();
  int b1;
  int b2;
};

B::~B()
{
  a1 = 900;
  b1 = 901;
  b2 = 902;
}

struct C : public B
{
  A *c1;
  A *c2;
};

// Stop the compiler from optimizing away data.
void refer (A *)
{
  ;
}

struct empty {};

// Stop the compiler from optimizing away data.
void refer (empty *)
{
  ;
}

int main (void)
{
  A alpha, *aap, *abp, *acp;
  B beta, *bbp;
  C gamma;
  empty e;

  alpha.a1 = 100;
  beta.a1 = 200; beta.b1 = 201; beta.b2 = 202;
  gamma.c1 = 0; gamma.c2 = (A *) ~0UL;

  aap = α refer (aap);
  abp = β refer (abp);
  bbp = β refer (bbp);
  acp = γ refer (acp);
  refer (&e);

  return 0; // marker return 0
} // marker close brace

When I compile this I see that the type of the "c1" field is bad:

 <2><48>: Abbrev Number: 5 (DW_TAG_member)
    <49> DW_AT_name : c1
    <4c> DW_AT_decl_file : 1
    <4d> DW_AT_decl_line : 46
    <4e> DW_AT_type : <0x116>
    <52> DW_AT_data_member_location: 2 byte block: 23 10 (DW_OP_plus_uconst: 16)
[...]
 <1><116>: Abbrev Number: 11 (DW_TAG_pointer_type)
    <117> DW_AT_byte_size : 4

That is, gcc claims that this field is a "void *", which is not the case.
