you're right, the BGL uses the default new operator to allocate memory 
which then isn't collected of course.
so this makes it effectively impossible to use BGL with boehm GC.
is there a boost guideline to allocate memory only through allocators 
which is violated here?

(the "new" which is causing the leak(or one of your leaks?) in your code 
is at line 278 of graph/detail/adjacency_list.hpp in version 1.32)
