Hi,
I am using r2 CVS with Linux 32-bit Intel g++ 3.4.1 as well as Linux
64-bit Opteron g++ 3.3.4 together with cheetah 1.1.4 & CVS and LAM 7.0.4.
I encounter crashes of r2/src/Particles/tests/bctest3 when running with
more than 10 contexts:
address@hidden:~/r2/src/Particles/tests/GPCEO$ mpirun -np 10 ./bctest3 -mpi
PASSED ... KillBC with expression
address@hidden:~/r2/src/Particles/tests/GPCEO$ mpirun -np 11 ./bctest3 -mpi
MPI_Recv: process in local group is dead (rank 8, comm 2)

CHEETAH-ON-MPI ERROR: Unrecognized get response tag -32766!
-----------------------------------------------------------------------------
One of the processes started by mpirun has exited with a nonzero exit
code. This typically indicates that the process finished in error.
If your process did not finish in error, be sure to include a "return
0" or "exit(0)" in your C code before exiting the application.
PID 26355 failed on node n0 (127.0.0.1) due to signal 8.

The problem seems to stem from the sync() call, some PatchFunction might
have a problem.
Thanks for your help,
