I tested with autolinking disabled and I tried to use 
libboost_unit_test_framework-vc80-mt-*.lib libraries explicitly.
I still get the same memory leaks dump.
The only difference is that when I use UTF library built
in debug mode (-gd) I  get more info (here I test UTF example 03):

D:\temp\utf_test>debug\utf_test.exe
Running 2 test cases...
./utf_test.cpp(11): error in "force_division_by_zero": check false failed
Detected memory leaks!
...
... here memory dump

but when I use UTF library built in non-debug mode I get only:

D:\temp\utf_test>debug\utf_test.exe
Running 2 test cases...

In both cases I get Windows dialog box with information about crash.

I also rebuilt UTF library using -d2 bjam option and I compared compiler 
options used by bjam with options I use to build examples in VC++ 8.0.
In both cases I use same options, double checked.

Do you have any idea where may be the problem that I get this memory 
dump when I use UTF lib built with bjam?
When I build UTF library with VC++ 8.0 project everything works well.
Simply, UTF seems to not to catch bugs in test examples properly.

Here, in example 03, I checked where debuger stops when I push Debug 
button in the crash dialog box:

// reports 'unknown location(0): fatal error in 
"force_division_by_zero": integer divide by zero'
i = i / j; // <------ HERE DEBUGER STOPS

but it should be handled by UTF as described in comments above, 
shouldn't it?

Thanks for any help

Cheers
