Replying to [comment:9 barry.wardell]:
- running without OpenMP (with a single thread)
Running on a single thread no longer triggers the segfault. So to summarize the combination required to trigger the problem: * Mercurial version of Carpet * Vectorisation enabled * Datura or Damiana (or at least not Kraken) * Optimisation (-O2) enabled * >1 OpenMP thread * Moving boxes AMR
and then the segfault happens in ggf::recompose_free_old(int).
