Hello all.  We are using ESIX for our product development, and would like
to have dereferences through null pointers produce core dumps.  Makes it
easy to find bugs.

The -z flag to ld is supposed to do this for you, handy dandy flag that it
is.  However, under ESIX, revs C and D, it doesn't work.  A transcript showing
an attempt to use the -z flag is included below.

My question is two-fold.  A) is this specific to ESIX or generic to
System V.3.2 on the '386?  B) Does anyone have an easy fix to make ld -z
work?

(BTW, over all, we really like ESIX; the price/performance can't be beat!)

Thanks in Advance.
