Description richard 1999-08-17 15:06:52 UTC 
I have a RH5.2 system with ncurses-4.2 and a RH6.0 system
with ncurses-4.2.  If I compile the following on RH5.2 and
then try and run it on RH6.0 it coredumps.

--------------------------------------
#include <curses.h>

int
main (int argc, char **argv)
{
  int c;

  initscr(); cbreak(); noecho();

  nonl();
  intrflush(stdscr, FALSE);
  keypad(stdscr, TRUE);

  c = mvinch(1,1);

  endwin();

  return c;
}

Cristian, is this expected behavior?
Comment 2 Kriang Lerdsuwanakij 2000-01-29 09:29:59 UTC 
I tracked down this problem recently.  The ncurses-4.2 that came with RH5.2
defined bool as 'char' while RH6.0 and 6.1 ncurses-4.2 defined it as 'int'.
So the incompatibility indeed exists.
