You can test it with STARPU_NCPU=1 STARPU_MAIN_THREAD_BIND=1 mpirun ./chameleon_stesting -o potrf. Without my patch, StarPU fails silently in its initialization, but yells and aborts when the first task is submitted. The failure in StarPU initialization is "normal": STARPU_MAIN_THREAD_BIND=1 retrieves one core to the number of cores; and in this case, there is no remaining worker available to execute tasks.
