Can someone please check out a libc_r tree as of 3 days ago and try that... There was a commit in libc_r/uthreads 2 days ago that might be relevant. failing that, can someone try newly compiled utilities on an older pre-KSE kernel? We need to eliminate one of these two changes... I think it's likely that it's breakage in signals from KSE but I'd like to know that before I tear even more hair out chasing this.. SO, I'm suffering from brain fade now.. but please, signals is known to be in dire need of cleanup after the KSE edit, (signals are delivered to processes but can effect individual threads. yuck) Anyone who can help identify the problem please do.. I'm off to bed before my head explodes.. I'll be back tomorrow AM. I'm going to spend as much of msuspension sleeping as possible :-) On Mon, 1 Jul 2002, Wesley Morgan wrote: > I see this problem too.
