DDD Problem: Can't Turn off Inferior Debugging (infrun)

Hi Folks,

GDB supports "inferior" debugging, and when it's enabled you get a lot 
of additional output like:

> infrun: infwait_normal_state
> infrun: TARGET_WAITKIND_STOPPED
> infrun: stop_pc = 0x1284db1
> infrun: stepping inside range [0x1284d50-0x1284de0]
> infrun: resume (step=1, signal=0)
> infrun: prepare_to_wait
> infrun: infwait_normal_state
> infrun: TARGET_WAITKIND_STOPPED
> infrun: stop_pc = 0x1284db3
> infrun: stepping inside range [0x1284d50-0x1284de0]
> infrun: resume (step=1, signal=0)
> infrun: prepare_to_wait
> infrun: infwait_normal_state

For some reason, I can't shut this off in DDD.  The gdb command to 
disable it is

   set debug infrun 0

I can type this in at the (gdb) prompt in DDD, but it only works until 
the end of the current debug session.  Then it comes right back.

There is a DDD dialog for GDB Settings.  It lists an option for Inferior 
Debugging.  This is always set to "infrun" in the dialog.

When I manually change it to zero to turn off inferior debugging, and 
click the Apply button it immediately changes back to "infrun".  If I 
click the Close button instead, it remains 0, but only until the end of 
the debugging session.

I keep the "Save Options" toggle checked in DDD's Edit menu.  Whenever I 
exit DDD, my ~/.ddd/init file says:

> set debug infrun \"infrun\"\n\

I can of course change it to zero in this file, but it is overwritten by 
DDD so this only works until the next time I exit DDD.

This does not seem to be a common problem.  I'm using ddd-3.3.9-1 on 
CentOS 4.4, if it matters.  I'm going to try manually setting it to zero 
in the init file and turning off "Save Options" to see if that works.

Thanks for any pointers...
