Date: Sat, 2 Feb 2008 22:08:05 +0100 From: Marcus von Appen To: sdl@lists.libsdl.org Subject: [SDL] [Patch] SDL-1.2 SDL_revcpy() asm patch for the cld flag Hi, as reported through the FreeBSD bug tracking system in SDL 1.2.13 (and in the 1.2 branch, if I see that correctly) the SDL_revcpy() macro sets the direction flag (std), but does not clear it afterwards (cld), which is wrong according to the GCC and SYS V specs. This can cause some weird side effects, which in turn can lead to memory corruption. You can read the full report with a detailed description and test program at http://www.freebsd.org/cgi/query-pr.cgi?pr=ports/120052 Attached is the submitted patch, which fixes the issue. Regards Marcus
