I just fixed this behavior recently, >fwiw. It's back to the way that it used to work. This looked so much like the problem that I'd had before, that I thought I should take a look at it. There was a race beteen EOF and signal processing. When the parent pty sent a signal, it also essentially sent an EOF. So, it was a race in the child as to which was processed. This may well have been a problem with my previous code, too. I checked in a fix. I hope. cgf
