Nope, I do this before my test: set target-async on set schedule-multiple on set pagination off set detach-on-fork off set non-stop on I can't say that I understand everything that happens in this mode. "run" appears to work in the background, which is mysterious to me. And, if I C-c gdb, I just get "Quit." back, and then gdb is in a weird state (I can't "continue" any inferior and if I try "run" I get an internal error). I am planning to debug these next; but if you know what is going on already... Tom
