 hi all,

 when compiling the xml parser to boost::property_tree with gcc and
 defining _GLIBCXX_DEBUG to enable stl debugging, my applications aborts
 with the following message:


 {{{
 /usr/include/c++/4.2/debug/safe_iterator.h:131:error: attempt to copy-
     construct an iterator from a singular iterator.

 Objects involved in the operation:
 iterator "this" @ 0x0xbfe46690 {
 type =
 N11__gnu_debug14_Safe_iteratorIN9__gnu_cxx17__normal_iteratorIPKcNSt6__norm6vectorIcSaIcEEEEENSt7__debug6vectorIcS7_EEEE
 (constant iterator);
   state = singular;
 }
 iterator "other" @ 0x0xbfe467e0 {
 type =

 (constant iterator);
   state = singular;
 }
 }}}

 the relevant part of the backtrace is:
