I just got a core file due to a segmentation fault.
The topmost few entries in the stack, according to dbx, are:

program terminated by signal SEGV (no mapping at the fault address)
(dbx) where

Unfortunately, I repeated the same thing again, and this time it did
not dump core...

STk-2.1.6 running on SunOS-5.3, compiled using gcc-2.6.3.

Let me know if there is anything more detailed you might want to see,
if this happens again...
