--- Comment #4 from Manuel LÃpez-IbÃÃez <manu at gcc dot gnu.org> ---
The reason is the in-class initializer. Move it and the previous definition
changes.

prog.cc:8:21: error: redefinition of 'const int foo<int>::u'
 const int foo<int>::u;
                     ^
prog.cc:6:11: note: 'const int foo<int>::u' previously defined here
 const int foo<int>::u = 0;
           ^~~~~~~~

I think it may be because of this code:

 /* Merge the initialization information.  */
      if (DECL_INITIAL (newdecl) == NULL_TREE
          && DECL_INITIAL (olddecl) != NULL_TREE)
        {
          DECL_INITIAL (newdecl) = DECL_INITIAL (olddecl);
          DECL_SOURCE_LOCATION (newdecl) = DECL_SOURCE_LOCATION (olddecl);
          if (TREE_CODE (newdecl) == FUNCTION_DECL)
            {
              DECL_SAVED_TREE (newdecl) = DECL_SAVED_TREE (olddecl);
              DECL_STRUCT_FUNCTION (newdecl) = DECL_STRUCT_FUNCTION (olddecl);
            }
        }
