Bruno, may I add bool sortParallel=True (by default) parameter into
insertionsortcollider to have an opportunity to switch it off, if
the simulation gives warning?

Thanks

Anton

Title:
  Segfault possibly in new parallel collider

Status in Yet Another Dynamic Engine:
  Fix Released

Bug description:
  I have got segfault, which is probably due to a new parallel collider.
  It happened on my "local" version, which is not yet merged to the main
  branch [1] (with ENABLE_LIQCONTROL=ON option), but it is unlikely due
  to my changes.

  Before the crash I have got the following warning several times:
  ERROR /home/gladk/dem/yade/trunk/pkg/common/InsertionSortCollider.cpp:132 insertionSortParallel: parallel sort not guaranteed to succeed; in chunk 1 of 2, bound descending past half-chunk. Consider turning ompThreads=1 for thread safety.
  ....
  ....
  Segmentation fault

  I will try to provide the minimal script, which produces such
  segfault. Bruno, maybe you have an idea, where it crashes?
