[Xquartz-dev] debugging flags?

I'd like to add a debugging flag that would choose between ignoring the "null pointer" errors (and letting them fall through to the rest of the code) for debugging purposes and trapping / reporting them (as is the default behavior). Right now, we have a couple different possible ways of turning on and off debug stuff -- creating dummy files is what i've done, but it's ugly. We could also set environment keys, or prefs plist keys. This would *not* be something most people would ever need to touch. Any thoughts? -- Ben Byer CoreOS / BSD Technology Group, XDarwin maintainer
