Can you spare some more info on this? 1. What is your /etc/src.conf and /etc/make.conf files? 2. Does your copy of sources has some third-party patches applied? 3. Does this happens on more than one PC i.e. are you sure hardware is not involved? Can you try to build world WITH_CLANG_IS_CC? Clang generated code is known to produce an instant coredump in situations where gcc generated code hits a loop or becomes unresponsive. -- Sphinx of black quartz, judge my vow.
