Using a debug build of 1.8.7, I'm still getting this malloc(0)
warning:
malloc debug: Request for 0 bytes
(coll_libnbc_ireduce_scatter_block.c, 67)
The simple code below should reproduce it:
$ cat ireduce_scatter_block.c
#include <mpi.h>
int main(int argc, char *argv[])
{
MPI_Request request;
MPI_Init(&argc, &argv);
MPI_Ireduce_scatter_block(NULL, NULL, 0, MPI_INT,
MPI_SUM, MPI_COMM_SELF, &request);
MPI_Wait(&request, MPI_STATUS_IGNORE);
MPI_Finalize();
return 0;
}
$ mpicc ireduce_scatter_block.c
$ mpiexec -n 1 ./a.out
