Comment (by rhaas):

 I can now reproduce this with a single thread and
 CarpetWaveToyNewRecover_test_1proc.par when running without mpirun and
 without MALLOC_DEBUG_ and not inside valgrind (but inside gdb). The
 original error seems to be memory corruption (double free) from inside
 Carpet/CarpetLib/src/mem.cc:178 which can be traced back to
 Carpet/Carpet/src/Shutdown.cc:102 (the delete f in Shutdown).

 Full backtrace:
