I don't have this problem (re: gcc crashing on buildworld, with or without WITH_CTF=1). If gcc is crashing with signal 11: http://www.freebsd.org/doc/en/books/faq/troubleshoot.html#SIGNAL11 Kindly requested: please apply some focus to a single issue or start separate threads for the problems you're experiencing (though I understand how some can be related to one another). So far there's been 3 or 4 separate topics/items mentioned during the course of this thread (how to get DTrace working, problems with devd, and now gcc crashing), and it's becoming more and more difficult to follow what's going on. -- | Jeremy Chadwick jdc@parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
