>Description:
Clicking 'Stop' button on Insight GUI blows away X session.
>How-To-Repeat:
Launch Insight from Source Navigator, to debug a C++ console app running in an xterm.
Click 'Run' then 'Continue', then while code is executing, click 'Stop'.
The X session appears to die immediately, and you're dumped back into gdm or whatever.
>Fix:
Problem appeared to be with function child_stop() defined in
file gdb/iftarg.c: Zero pid value being passed to kill().
I hacked around this by changing child_stop to do the following
instead:

  if (inferior_pid)
    kill (inferior_pid, SIGINT);
