This patch is not OK, but it's close.
We should not call unshare_expr on DECL_INITIAL until after the
mark_used call, as static data members in templates will not have proper
initializers until after that point. Also, there's no need to unshare
*before* calling fold_non_dependent_expr.
In fact, there's no need to unshare before the return statement at the
end of the function. That will avoid creating trees that will only be
thrown away later.
So, why not just do:
return unshare_expr (decl);
at the end of the function?
