Public bug reported:

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?
