Hey, I am glad someone else has seen odd behavior with a 3/50 and prom
version 2.3 [I was *really* beginning to suspect a defective machine].
I run this Sun diskless and use a NetBSD/i386 box as a fileserver.  I
know that the Ethernet card on the fileserver is *way* slow, and
thought that it was perhaps related to swapping over NFS, but I don't
know for sure.  Basically, I can always make a compile of 'tcsh' drop
core, usually before it actually gets to compiling anything
[i.e. which it is generating the various header files, basically a
couple of 'egrep's and a 'sed' in a single pipeline].  After it starts
dropping core, *any* binary which uses shared libraries will drop
core.  Static binaries seem to work better.

Sometimes it will just start to drop core on boot [important things
like getty and the like].
