I'm currently running a fairly up-to-date HEAD: FreeBSD mac.draftnet 8.0-CURRENT #0: Tue Jun 16 22:07:11 BST 2009 brucec@mac.draftnet:/usr/obj/usr/src/sys/IBOOK powerpc The problem I see is that after a few hours of running buildworld, when it starts building clang itself, 'as' crashes with a signal 11. I'm wondering if this is the normal case of bad memory/HDD/CPU or something else because it also causes several other processes to crash, notably dhclient and sendmail, but I've also seen tcsh crash too. I created a test program which allocated 500MB memory to force the system into swap (my iBook only has 512MB). After a few minutes dhclient crashed but the test program kept running. Is this what normally happens when hardware's going bad? -- Bruce
