在`libpmpi.12.dylib`中使用MPI_Barrier时出现分段错误

我使用brew install mpich ，但是如果我使用MPI_Barrier ，我会得到分段错误。 请参阅以下简单代码：

 // Ac #include "mpi.h" #include  int main(int argc, char *argv[]) { int rank, nprocs; MPI_Init(&argc,&argv); MPI_Comm_size(MPI_COMM_WORLD,&nprocs); MPI_Comm_rank(MPI_COMM_WORLD,&rank); MPI_Barrier(MPI_COMM_WORLD); printf("Hello, world. I am %d of %d\n", rank, nprocs);fflush(stdout); MPI_Finalize(); return 0; } 

mpicc Ac -g -O0 -o A

运行mpirun -n 2 ./A ，我收到以下错误：

  ================================================================================== = = BAD TERMINATION OF ONE OF YOUR APPLICATION PROCESSES = PID 60914 RUNNING AT pivotal.lan = EXIT CODE: 139 = CLEANING UP REMAINING PROCESSES = YOU CAN IGNORE THE BELOW CLEANUP MESSAGES =================================================================================== YOUR APPLICATION TERMINATED WITH THE EXIT STRING: Segmentation fault: 11 (signal 11) This typically refers to a problem with your application.

来自lldb -c /cores/core.60914的详细堆栈：

用法从官方指南中复制。 MPI_Barrier函数实现的问题是什么？ 谢谢。
