Again, I tried something like below. for (recursive_directory_iterator itr(root, ec), itr_end; itr!=itr_end; ) { ... ; itr.increment(ec); if(ec) itr.pop(); } This time itr.pop() assertion fails because "pop() on recursive_directory_iterator with level < 1"

Anybody got some advice? Thanks.

For others facing the same problem, I've reported it as a bug and created Ticket #5403(https://svn.boost.org/trac/boost/ticket/5403). A fix was also attached
