Date: Sat, 10 Jul 2004 21:02:33 +0200 From: "Philippe Plantier (ayin)" Subject: [SDL] Problems allocating large surfaces There are problems when allocating large surfaces using SDL_CreateRGBSurface. When, for example, we try to allocate a surface wider than 16384 pixels, the calculation of the pitch overflows; this leads to a surface that has the w and h flags correctly set, but whose "pixels" buffer is too small. That may lead to heap corruption.
