This is the last entry in my possible solutions list :-). I also
searched trac, for a bug similar to my, I didn't find any.

Today, i know a little bit more about the bug:
* it happens in "match" algorithm only, "search" algorithm works as expected
* wregex, and regex ".getloc().name()" expression returns same data.
* I also found out, that the functionality works fine with boost 1.32.
However, the product I am working on, has been changed a lot too.

My possible solutions list:
* use search algorithm and check whether the found string is the whole string
* use regex with ICU. We have ICU 3.4.
* upgrade boost.

What do you think?

Thank you for help.
