mwm dumps core on HP-UX systems with a floating point exception

[Allen Wong_1]

Whenever we try to execute mwm on our HP-UX systems, it dumps core:

# export DISPLAY=localhost:1.0
# /usr/bin/X11/mwm
Floating exception(coredump)

We are using Xvfb on HP-UX 11.11 with these settings:

Xvfb :1 -screen 0 72x72x8 -fp /usr/lib/X11/fonts/misc/ -noreset


We used gdb on the core file to try to determine the cause:
# /opt/langtools/bin/gdb /usr/bin/X11/mwm core

(gdb) bt
#0 0x1e88c in InitIconPlacement ()
#1 0x40010490 in ?? ()

We suspect that this may be caused by the low Xvfb setting (72x72x8) but we can't easily test this by bouncing the frame buffer (it's a production system). We would have a better chance to be granted downtime if we had a more definitive explanation. Any suggestions would be greatly appreciated. Thanks.

Allen,

At the risk of being obvious, have you applied the latest Motif patches?

Pete,

Patch PHSS_28370 was applied but it has been superceded by PHSS_28875. We'll patch again. Hopefully, this will solve the problem. Thanks.
