Gordon,
Let me first express my gratitude to the work you are doing.

I think the problem still isn't solved yet. But I don't think
you are surprised to hear this. :-(
When I use the stuff, that was available on:
Fri Jul 1 12:57:30 MET DST 1994
I get the following message on the console, when trying to
run `csh':
panic: trap: sig not set
I don't know what's causing this, but maybe you can use
this information to solve this dreaded VM bug.

No, I already was using DDB before.

I'am puzzled about this. I don't use the -g option at all.
There must be another explanation.
The `config' I did use, follows:
----------------------------------------
#
# new config file for HILTON
#
include "std.sun3"
# Machines to be supported by this kernel
options "SUN3_50"
# Needs to be set per system. i.e change these as you see fit

options DST=2 # daylight savings rules (for param.c)
# Standard system options
options SWAPPAGER, VNODEPAGER, DEVPAGER # paging
options KTRACE # system call tracing support
#makeoptions DEBUG="-g" # symbols for kgdb + nm
# I use DDB by copying in the symbols with /usr/sbin/dbsym.
options DDB
options SYMTAB_SPACE=72000 # was 72000

Using dbsym, I get the following information:

Does this differ much with what you get?
Maybe my development environment isn't OK!
I'am using:
gas: 2.3
gcc: 2.5.8
ld: SUNOS 4.1.1_U1
To this message, I attached the output that is given by `ls -l'.
Anything weird about this?
Kind regards,
Harry Schreurs
P.S. Can you put announcements of source changes, that are relevant
to the sun3-port also in the `port-sun3' mailing list? I don't get
the `source-changes' mailing list anymore and I'm also unable to
get back on this list!
