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
