The last time I was able to "successfully" build -current on my PC164SX
was Dec 25th. Since then, when starting with a freshly built kernel (and
current -current) my "make build" tends to die.  Earlier in January it
would fail with the huge clean in libc (massive argv list) - ending with
a signal 11 death. So I'd simply return to my old kernel and wait til
I was home again to try with a newer -current.  With a fresh sup from
Friday (Jan 28) I see the following:  with a new GENERIC kernel, as soon
as the new shared libc is installed, the next command faults with signal
11.  Lots of commands do (I suspect those relying on shared libc).  I
happened to have an old system image circa last September, and when I
drop libc.so.12.45 in place, replacing the link to the current 12.54,
everything appears to work again. What the heck have I done wrong here? 
Did I miss rebuilding some part that has left me in a dead-end state? 
Thanks for any suggestions!  -- Ken
