No, that's not the problem.  Apparently the introduction of per-thread
CPU-time clocks broke this application.  The clock changes introduce
new members in the datastructures which in turn change the layout and
the size of these datastrucutures.  In theory this should be under
the hood and the applikation doesn't know about this, but somehow...

I'll have a look with a debugger after dinner.
