Yes, I always run fsck -f twice, to make sure that any errors
were really fixed -- and in this case they were fixed.

Yes, the same problem, and rebuilding gmake was the first thing
I tried -- it didn't change anything.  I made one big mistake in
my original post -- the build does *not* always stop in the same
place.  It does always stop just after printing 'leaving directory
foo', so the error is not completely random (just partly random).

I've spent all morning trying to get a ktrace of the problem
without success.  ktrace.out keeps using up all my free disk
space -- I made room for a 10GB partition, and that just got
filled up.  I've been running kdump on the result for 35 minutes
now and it just keeps scrolling by on my screen.  Dunno if I'll
be able to tell anything when it finally stops.  This process
does not scale well!
