#1087: qc0-mclachlan fails with Assertion `not reg.processors' failed

 I am running qc0-mclachlan.par from the ET trunk on Datura.  I get this
 error message during startup:

 cactus_sim:
 /home/ianhin/Cactus/EinsteinToolkit/arrangements/Carpet/CarpetLib/src/region.cc:166:
 void combine_regions(const std::vector<region_t, std::allocator<region_t>>
 &, std::vector<region_t, std::allocator<region_t>> &): Assertion `not
 reg.processors' failed.

 I get the same message whether I run on 1 MPI process or 2, and also on
 another machine.  Since qc0-mclachlan is a standard BBH simulation, I
 assume that a similar error could/does occur for any binary simulation
 with moving-boxes mesh refinement.  Setting priority to Critical as a
 result.
