Stack overflow when grouping uses itself

[dreamesee]

The following incorrect yang file (because a grouping certainly does not need to use itself):

module any_mod_name {
  namespace "any_mod_name";
  prefix "any_mod_name";
  grouping stuff-top {
    uses stuff-top;
  }
}

Produces:

ASAN:DEADLYSIGNAL

Hi,
should not happen with most recent master or devel.
