+Subject: [PATCH 1/2] base/mpi.cc: remove superfluous explicit instantiations
+ of template variable
+
+The `mpi.h` header already contains:
+```
+template <typename T>
+const MPI_Datatype mpi_type_id_for_type = /* implementation detail */;
+```
+Meaning, the variable is known fully after including the header.
+Furthermore, the `const` qualifier marks the (template) variable as
+`static`. I.e., it has internal linkage.
+
+Thus, we must not explicitly instantiate the variables (suggesting
+"extern" linkage in all but the `mpi.cc` compilation unit). This
+apparently not an issue with OpenMPI because `MPI_Datatype` is a
+complex data structure. But it is an issue with mpich where
+`MPI_Datatype` is a simple `int` - leading to a segmentation fault when
+during program startup.
