Hi,
I am using Intel MPI Library 5.1.2.146 and Intel C++ Compiler 16.0.1.146 under Windows 7 Professional x64.
The following program:
#include <mpi.h>
int main(int nArgC, char *apszArgV[])
{
MPI_Comm comm;
MPI_Init(&nArgC, &apszArgV);
MPI_Comm_dup(MPI_COMM_WORLD, &comm);
MPI_Finalize();
}built with the following command:
mpiicc -check_mpi send_leak.c
and run with the following command:
mpiexec^ -hosts stu003-home -n 2^ -trace-pt2pt^ -trace-collectives^ -print-rank-map^ send_leak^ --itc-args --check-tracing ON
gives the following output:
... [0] WARNING: EXCEPTION_ACCESS_VIOLATION occurred [0] ERROR: Signal 3 caught in ITC code section.

In fact any MPI call that creates a new communicator (not only MPI_Comm_dup()) leads to the same result.
Please help with my problem. Thanks in advance!
