Subject: [PATCH] liboctave: Fix memory allocation check in
 octave_sort<T>::MergeState::getmemi

* liboctave/util/oct-sort.cc (octave_sort<T>::MergeState::getmemi):
  Check both m_a and m_ia before returning early. The original code
  only checked m_ia and m_alloced, which could lead to undefined
  behavior if m_a was not allocated.
