Carpet commit c8eecbe1968f breaks gcc compilation

[Tanja Bode]

I get the following fatal error when compiling the latest development ET, fresh checkout, with gcc 4.6.

1. !div style="font-size: 70%" #!python COMPILING .../CarpetLib/src/gdata.cc .../CarpetLib/src/gdata.cc: In function 'MPI_Datatype mpi_datatype(const slab<T, D>&) [with T = int, int D = 3, MPI_Datatype = int]': .../CarpetLib/src/gdata.hh:42:43: instantiated from here .../CarpetLib/src/gdata.cc:51:21: error: uninitialized const 's' [-fpermissive] .../CarpetLib/src/gdata.hh:27:8: note: 'const struct slab<int, 3>' has no user-provided default constructor

I tracked it down to Carpet commit c8eecbe1968f (11. Jan). Is somebody hiding a patch with a constructor or is there another fix?

you need a constructor in 'struct slab'. An empty one will do. I'll commit a patch (had already written it for myself)...
