Created attachment 159628 [details] path that fixes the memory leak The 'config' program leaks memory when running. It's not critical, in that config isn't a long running program, but it easy to fix. The clang static analysis tool found the problem originally. Patch is attached. I've been running with this patch for a couple of months on my -current tracking machine, and not had any problems.
