That's definitely the simplest solution.  But I have to admit that
returning a bare pointer to a heap-allocated object leaves a bit of a
bad taste in my mouth, especially since there are tools available in
C++ (e.g. smart pointers) to significantly reduce the risk of memory
leaks in user code.

That's a good point -- I'd never actually looked into the stability of
boost libraries before.
