Well, my system has been up for a week or so... (oops, my wtmp got
rolled a couple of minutes ago, so last after a reboot doesn't help.
At least two weeks I think)
  Compiling, running xemacs, etc.. lots of stuff with the sup'ed
kernel of early April. 
  Then, just now, it started core dumping again on shared library
stuff. 
  This suggests that whatever changes were made wrt the mmap code
(discussed at length on the sparc list) have a partial effect...
