Since I have committed the patchset for 11734 and 12273, I am now revisiting
this bug...

There /appear/ to be multiple problems with symbol lookup that cause this
failure.  I have further reduced the test case to:

#include <stdlib.h>

typedef const char* const* my_type;
typedef my_type my_other_type;

void
test (my_other_type foo) { }

int
main (void)
{
  test (NULL);
  return 0;
}


Breaking on "test(my_other_type)" works, but breaking on either "test(my_type)"
or "test(const char* const*)" does not.  This partly occurs because
dwarf2_physname calls c_type_print_args, and that function does not do any
typedef resolution (which it should when it is used to compute physnames). 
Unfortunately, fixing that still doesn't work right, either.

But I just wanted to update this bug to let anyone watching it know that I am
taking a look at it.
