This is with a debug build of 1.8.5
I'm getting segfaults with tests related to the use of
MPI_Type_create_f90_{real|complex}. See below the attached test case
and the valgrind output (BTW, MPI_Type_create_f90_integer seems to be
OK).
$ cat type_f90.c
#include <mpi.h>
int main(int argc, char *argv[])
{
MPI_Datatype datatype;
MPI_Init(&argc, &argv);
MPI_Type_create_f90_integer(4, &datatype);
MPI_Type_create_f90_real( 6, 30, &datatype);
MPI_Type_create_f90_real(15, 300, &datatype);
MPI_Type_create_f90_complex( 6, 30, &datatype);
MPI_Type_create_f90_complex(15, 300, &datatype);
MPI_Finalize();
return 0;
}
