wd and ps crashes Proc32

QNX Newsgroups (Archives) qdn.public.qnx4

This is a follow-up on the (rather long) thread
“/bin/wd and Proc32 crash”.

The following steps crashes Proc32 (here at my site).

  1. A fresh install from “QNX Product Suite CD July 2003” of

QNX 4.25
Photon 1.14 runtime
Watcom C 10.6
TCP/IP

with all relevant patches.

  1. Configure TCP/IP
    add ‘qnx1’ entry in /etc/hosts
    modify /etc/config/bin/tcpip.1 (attached)

  2. Reboot

  3. Log in as root

  4. Start Photon (ph)

  5. Open a pterm and type wd

  6. Open a pterm and type ps

and Proc32 crashes. I assume it is the same
dump message as before, attached below.

If I reboot and press ESC for alternate boot image
it doesn’t seem to crash, not even after running tcpip.1
manually.

If I reboot, slay Socket, Proc32 crashes anyway.

But the behaviour is not consistent. If I mask out
all entries in tcpip.1, I still get Proc32 crashes.

Comments ?

I have simplified the steps to make Proc32 crash even further.

  1. Install

QNX 4.25
Photon 1.14 Runtime
Watcom C 10.6

  1. Add

export DUMMY=DUMMY

before test of tcp.1 in sysinit.1

  1. reboot

  2. start Photon (Pg.vg4 driver)

  3. open a pterm and type wd

  4. open a pterm and type ps (sin does NOT make Proc32 crash)


    I really hope you are able to reproduce this crash.
