[boost] Unit test FP comparisons - memory leaks in debug

I have tried to use the Boost 1.33 Unit test FP comparison with MSVC 8.0
beta 2 and the example

test_fp_comparisons.cpp works as expected in release mode (runs 5 tests ok)
(Though not auto - Had to run it myself). Defines WIN32;NDEBUG;_CONSOLE

but in debug mode I get:

Can anyone throw any light on this please?

Thanks
