Yes. And you will catch it if you know what you're doing. If you don't,
you won't, simple as that.

I'm not saying you can't catch things like that, I'm saying that if you
don't know this can happen, it's very likely you won't catch them. And
if one just blindly follows whatever dh_* stuff spews out, without
understanding what and why they do, the chances increase.

That's all I'm saying: use the tools, but don't blindly trust them.
