Maybe LD_POINTER_GUARD wasn't set at my first attempt then (or maybe I hadn't updated), but if it's a security feature then I'm a bit surprised you can override it just by setting an environment variable (if it was needed/used for compilation then that would provide a choice over the level of security). As a side note to Eli, perhaps we should mention it in the Emacs DEBUG file. -- Nick http://www.inet.net.nz/~nickrob
