little(?) bug...

Hi,

While Valgrinding my application, I found a problem in ncurses 5.2.20020112a. 
The following minimal test case:

   #include <curses.h>

   int main(void)
   {
      initscr();
      start_color();
      use_default_colors();

      refresh();

      endwin();
      return 0;
   }

causes Valgrind to tell:

   ==18127== Conditional jump or move depends on uninitialised value(s)
   ==18127==    at 0x4024CB86: _nc_do_color

Hope you can use that somehow...
