Now I think it is a compiler/optimizer bug. After I recompiled libc and rm without optimization, the bug has disappear. But later, in make buildworld, I noticed another problems: for example, strip(1) and nm(1) sometimes die too... Well, now, after several rounds, make buildworld going on, it is now pretty far, and I hope this time it will succeed. (BTW, nm(1) failures apparently were fixed by recompile of /bin/sh without optimization. I applied the gcc patch from your page and tried build /bin/sh with -O - it didn't help). I am still very confused. Am I the first man who ever tried to install 19990206-SNAP? Anyone build world without any optimization, right? I don't actually believe that the answers are "yes"...
