Boehm garbage collector for C++ exists. But it's rarely used in real life.

Yes, unfortunately.
There is small paragraph near the end full of incoherent rumbling.
The 3rd Edition is much better in that regard. It has 3 reasonably wriitten paragraphs. It explains how GC and destructors poorly interact with each other
and gives recommendations (essentially "Don't use non-trivial destructors" to
users that still think that GC in C++ is good idea.
But 3rd Edition is rather old, too. Since the large part of C++ user's community fall in love with RAII design pattern, so for them Bjarne's suggestions would probably sound as heresy.
Now, the funny thing is that Stroustrup *invented* RAII.
