The problem is that a number of them seem to be quite unreliable. I've see= n test runs where gdb.btrace/step.exp and/or stepi.exp have a pile of failu= res, but then when I rerun either just those tests, or the whole suite, the= y pass. Since I haven't a clue how the reverse execution stuff works, I don't know = if this is expected. It seems strange. I also don't know what to do about= it if it's not supposed to be like that. For now, I'm just running things = a couple of times, and if they pass once, I call it good enough. paul
