 Priority:  major   |   Milestone:                     
Component:  Carpet  |     Version:  development version

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

 {{{
 #!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.cc:51:21: error: uninitialized const 's'

    .../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?
