Ah, but I _have_ managed to get /bin/sh to core dump with a segmentation
fault under SunOS 4.0*.  "file core" tells me that the core file is indeed
from /bin/sh.  It occurs when either the command line is very long or the
environment is very large.   It has bitten me several times in "make".  
Sun sent us a patched version of /bin/sh to fix it, and I beleive it has 
fixed the problem.  If you are running into this, you should probably get
in touch with Sun about it...
