[boost] [PropertyTree] Help tracking down test failure.

Hi, If you look at the PTree regression results: http://www.boost.org/development/tests/trunk/developer/property_tree.html you'll see that the test_property_tree test currently fails on a log of platforms, especially Darwin. An assertion fails. Since I cannot reproduce the error on any of my systems, could someone who can please send me a stack trace, and perhaps a debug print of the two objects involved? Here's the test output of one runner: http://www.boost.org/development/tests/trunk/developer/output/minion-mpi-boo... I'd like the debug representations of 'this' and 'o', please. Thank you, Sebastian
