Summary: Is there a bug fix out there?

I'm running HP/UX 7.0 on an HP 9000/835, with a hp98731 graphics
accelerator and HP's distribued X11R3. (whew) My X server is
running in the 98731's overlay planes.

I've repeatedly noticed that while debugging a program with xdb,
if you hit ctrl-C while the program is in the midst of starbase
calls, the computer will lock up. The pointer doesn't move, and
the offending process must be killed from another terminal.

When the process is killed, xdb always notes that the process was
stopped at about the same place:

interrupt (ignore) at 0x000922b4
(file unknown): _hp_davinci_wait +0x0000005c: (line unknown)
>

Does anyone know a way around this bug so that I can debug programs
that use starbase?

Thanks much,
--Harold
