         error if symbols aren't loaded, but GDB calls the expression
         evaluator in all sorts of contexts.

         For example, commands like `set width' call the expression
         evaluator to evaluate their numeric arguments.  If the
         current language is C, then that may call this function to
         choose a scope for macro expansion.  If you don't have any
         symbol files loaded, then get_current_or_default would raise an
         error.  But `set width' shouldn't raise an error just because
         it can't decide which scope to macro-expand its argument in.  */
