is commented back in it does fail. I am not sure exactly how a debugger will help in this case since the colorset call goes directly to the ncurses library. If in fact that the issue is the ncurses library then it seems that there is no feasible solution until that library is fixed, in which case this patch is sort of useless. ... erg = colorset(colorpairnumber, NULL); // Debating on forcing null

What is color_pair_number in the C code? If it's some incorrect value (-1? 255?), maybe ncurses is indexing off an array and crashing.

This is why a debugger might help; you could run the test program until the crash and then print out the values of the relevant variables. e.g. is stdscr set to a non-NULL value? There might be a debugging version of ncurses that will let you look at the variables inside the ncurses code, which may make the problem clear.
