Yes I can.

bjam debug

I got: bin/gcc/release/...
I expected: bin/gcc/debug/...

bjam release

I got: bin/gcc/debug/...
I expected: bin/gcc/release/...

As I was investigating properties, I ran into some logic that looked
really weird in "main-target.apply-default-build", so I tried this
simple example and got results that looked weird too.

Volodya's change fixed this problem.

The underlying issue, however, is that processing of properties is so
confusing and distributed among so many functions and objects, I think
nobody can guarantee that all the functions do the right things. I'm
working on understanding the requirements.
