Under the load (make -j20 buildworld) the compiler or make(1) often die with signal 11. I found in mailing lists that there is similarly looking problem with -current, any chances that -stable is affected as well? Adding `options DISABLE_PSE', as suggested, reduced the likelyhood of the problem, but didn't eliminate it completely (-j20 fails with sig11 from time to time, but much less frequently than without the said option. Any ideas? -Maxim --ikeVEW9yuYc//A+q Content-Type: text/plain; charset=koi8-r Content-Disposition: attachment; filename=dmesg Copyright (c) 1992-2002 The FreeBSD Project.
