Right. And that's what I'm complaining about. You're talking about
intermediate values generated every time the inferior stops and the watchpoint
expression is evaluated, right? That's what I'm thinking about.

If you're just thinking about the values stored in struct breakpoint, then I
agree with you...

Yes, and I'm complaining about not GCing for a great, out-of-our-control,
while...

Am I having a delusion here? :-)
