running loopcontrol on strange number of threads fails

[Roland Haas]

my machine has 8 cores (according to /proc/cpuinfo). Running eg the trigger test with 3 threads fails inside of loopcontrol.

To reproduce:

export OMP_NUM_THREADS=3
mpirun -n 2  exe/cactus_bns_all arrangements/AEIThorns/Trigger/test/trigger.par

Keyword: LoopControl

This still happens even with current (Sun Mar 22 18:46:21 CET 2015) trunk, though failure looks a bit different now:

actus_sim: /data/rhaas/postdoc/gr/ET_trunk/configs/sim/build/LoopControl/loopcontrol.cc:312: T {anonymous}::divexact(T, T) [with T = int]: Assertion `i % j == 0' failed
