Hi Jack, I may need to see the whole code to decide but my quick look suggest that ptmalloc is causing a problem with STL-vector allocation. ptmalloc is the openMPI internal malloc library. Could you try to build openMPI without memory management (using --without-memory-manager) and let us know the outcome. ptmalloc is not needed if you are not using an RDMA interconnect.
With best regards, -Belaid.

Because the code is very long, I just show the calling relationship of functions.
