If you look closely you can see that mr->ms->s is involved in all cases (the static part of the menu style). Mikhael posted a similar core dumps a few weeks ago. In his and one of the similar crashes I got, the contents of mr->ms had been overwritten with random data, so mr->ms->s pointed to a random location. > I am quite sure that I checked if the > pointer mr or its subpointers were NULL before accessing it to prevent > the seg fault.
