[Bug c/18166] New: top const stripped in structs for C

[mrs at apple dot com]

The following doesn't produce accurate dbx stabs information on powerpc-apple-darwin:

struct ssc { char * const ptr; };
struct ss { char * ptr; };

int main ()
{
  struct ssc xssc;
  struct ss xss;
}

(gdb) ptype xss
type = struct ss {
    char *ptr;
}
(gdb) ptype xssc
type = struct ssc {
    char *ptr;
}

http://gcc.gnu.org/ml/gcc-patches/2002-10/msg01872.html has a wrong patch.  The corresponding 
C++ code works as expected.

For reference, the C++ version:

struct ssc { char * const ptr;
  ssc () :ptr(0) { }
};
struct ss { char * ptr; };

int main ()
{
  struct ssc xssc;
  struct ss xss;
}

and its output:

(gdb) ptype xss
type = struct ss {
    char *ptr;
}
(gdb) ptype xssc
type = class ssc {
  public:
    char * const ptr;

    ssc(ssc const&);
    ssc();
}

My patch <http://gcc.gnu.org/ml/gcc-patches/2005-01/msg02180.html>
should cause fields to be given the correct types within the C front
end, and might thereby fix this bug.

Could someone with a Darwin build to hand check whether this bug is indeed fixed
as I suggest in my previous comment?

Confirmed as fixed:
(gdb) ptype xss
type = struct ss {
    char *ptr;
}
(gdb) ptype xssc
type = struct ssc {
    char * const ptr;
}
