As far as I can tell -- I haven't tested it -- Debugger() only
breaks if the USERBREAK environment variable is set to 1. In
that case it sends a SIGINT to the current thread. That's not
quite the same as a SIGTRAP.
Is there some condition whereby using another mechanism would be
better, for example running directly from gdb instead of the IDE?
I ask only because I've never had a reason to not use Debugger().
I think -- though the debugger folks might correct me on this --
that trap/int3 is what gdb itself uses for breakpoints, so in
theory it might be "better" somehow. But as long as you're
debugging a program that doesn't have its own SIGINT handler, I
think they'll have the same effect.
