Disclaimer: this is for trunk svn up'ed yesterday.
The code below should fail with ERR_COMM, but it succeed...
#include <mpi.h>
int main(int argc, char **argv)
{
int *value, flag;
MPI_Init(NULL, NULL);
MPI_Comm_get_attr(MPI_COMM_NULL, MPI_TAG_UB, &value, &flag);
MPI_Finalize();
return 0;
}
Additionally, this is really not a bug, but I'll comment about it
anyway (I think I've commented about this some time ago)...
I would expect the two codes below to fail with MPI_ERR_KEYVAL, but
they fail with MPI_ERR_OTHER...
#include <mpi.h>
int main(int argc, char **argv)
{
int *value, flag;
MPI_Init(NULL, NULL);
MPI_Comm_get_attr(MPI_COMM_WORLD, MPI_KEYVAL_INVALID, &value, &flag);
MPI_Finalize();
return 0;
}
#include <mpi.h>
int main(int argc, char **argv)
{
MPI_Win win;
int *value, flag;
MPI_Init(NULL, NULL);
MPI_Win_create(MPI_BOTTOM, 0, 1,
MPI_INFO_NULL, MPI_COMM_SELF, &win);
MPI_Win_get_attr(win, MPI_KEYVAL_INVALID, &value, &flag);
MPI_Win_free(&win);
MPI_Finalize();
return 0;
}
