AttributeError: 'module' object has no attribute 'InvalidPersistentRequest'

Hello,

The following program raises an error in Aislinn:

#include <mpi.h>
#include <stdio.h>
#include <stdlib.h>

#define buff_size 128

int main(int argc, char **argv) {
  int nprocs = -1;
  int rank = -1;

  MPI_Init(&argc, &argv);
  MPI_Comm_size(MPI_COMM_WORLD, &nprocs);
  MPI_Comm_rank(MPI_COMM_WORLD, &rank);
  printf("Hello from rank %d \n", rank);

  if (nprocs < 2)
    printf("MBI ERROR: This test needs at least 2 processes to produce a bug!\n");

  int dest = (rank == nprocs - 1) ? (0) : (rank + 1);
  int src = (rank == 0) ? (nprocs - 1) : (rank - 1); 

  int buf1[buff_size]; MPI_Request req1;
  int buf2[buff_size]; MPI_Request req2;
  MPI_Send_init(buf1, buff_size, MPI_INT, dest, 0, MPI_COMM_WORLD, &req1);
  MPI_Start(&req1);
  MPI_Irecv(buf2, buff_size, MPI_INT, src, 0, MPI_COMM_WORLD, &req2); 
  
	 /* MISSING: MPI_Wait(&req1, MPI_STATUS_IGNORE); */ 
	 MPI_Wait(&req2, MPI_STATUS_IGNORE);  
	MPI_Request_free(&req1);
	MPI_Request_free(&req2);

  MPI_Finalize();
  printf("Rank %d finished normally\n", rank);
  return 0;
}

Here is the output of Aislinn in this case:

 $ aislinn -p=2 MissingWait_Send_init_Irecv_nok

Thanks for this tool,

Thank you for your bug reports.

I will try to fix them; however, I need to first migrate Aislinn code on a newer Valgrind so I can run it with my current gcc, and it may take me some time.
