See the code below. As expected, you DO get an error (though the error
is ERR_INTERN, somewhat not informative). However, if you fist
create() % destroy a windows, you DO NOT get any error. This is VERY
strange, right? I understand this issue is going to be very low
priority for you, but I'm wondering whether this is actually related
to some deeper, nasty bug that can cause actual trouble in valid code.
#include <mpi.h>
int main(int argc, char *argv[])
{
MPI_Init(&argc, &argv);
#if 0
{
MPI_Win win;
MPI_Win_create(MPI_BOTTOM,0,1,MPI_INFO_NULL,MPI_COMM_SELF,&win);
MPI_Win_free(&win);
}
#endif
{
MPI_Datatype byte = MPI_BYTE;
MPI_Type_free(&byte);
}
MPI_Finalize();
return 0;
}
