Thanks for the report. It's a bug.

To get a workaround, modify allocate_many_and_construct() function of boost/container/detail/node_alloc_holder.hpp file so that if "n" is zero, no code is executed. This function should do nothing if "difference_type n" argument is zero (as it's your case, since the source container is empty.
