Debig an infinite loop

Pointers on debug'n, especially tracking an infinite loop.

Also is there a Ruby "binding" for ddd?

Thanx.

My preferred method of debugging is to open an irb shell from the program.
This lets you evaluate local variables, etc. See Florian Weber's recent
"breakpoint.rb" announcement.

  loop do
    ...
    breakpoint if some_condition
    ...
  end

For an infinite loop, I'm guessing printf-debugging would help as well.
Thus: puts/logger/log4r.

I sincerely doubt it.

Cheers,
Gavin

Yes, that seems pretty nice. I plan to use that.

Although I did figure it out already, it was tricky b/c the loop was occurring
in someone else's library.

Too bad.

Thanks,
