From: Mike Frysinger <vapier@gentoo.org> To: sdl@libsdl.org Date: Sun, 11 Dec 2005 22:57:37 -0500 Subject: [SDL] exec stack in libsdl update i posted back in September a patch to remove executable stacks: http://www.devolution.com/pipermail/sdl/2005-September/070626.html later in November, a similar patch was merged it seems: http://www.libsdl.org/cgi/cvsweb.cgi/SDL12/src/hermes/mmx_main.asm however, this lacks the additional output format checks that i posted in my patch ... this isnt a problem if the hermes asm code is only ever used to produce ELF objects, but if this is not true, then the additional checks in my original patch will need to be merged -mike
