GDB works correctly. Did not check with lldb, but it also should work. The result is similar to the debug info, produced for the next code:

  struct {
  short : 3;
  short : 6;
  } a;

But the code, produced by the compiler, is also the same. So, I think, the debug info also should be the same.

It does not affect the next fields. We point exactly to the bytes, allocated for this particular bitfield only.
