[Super-tux-devel] Segmentation fault in gameloop.c

[Armin D. <ar...@ar...>]

In function 'shape' the following code may lead to a segmentation fault
if yy is exactly 15, because the
array tiles has got only 15 elements (0 to 14).

  if (yy >= 0 && yy <= 15 && xx >= 0 && xx <= level_width)
    c = tiles[yy][xx];

Changing the '<=' to '<' will fix this, I think..

I encountered this using MinGW on a Windows XP machine, where the blue
screen guys look somewhat familiar...

Thanks, but this has already been solved in CVS. :)
