----------------------------------------------------+-----------------------
 The following code:
 {{{
 boost::filesystem::path p1("c:\\123"), p2("c:\\987");

 ASSERT_EQ(p1, p2);
 }}}

 leads to stack overflow.
 It's because when GTest prints the assertion values it examines `path` as
 a container and try to print its items which are also `path` instances.
 This leads to recursion and stack overflow.

 Most probably, the problem should be solved at Gtest side, but personal I
 think the design when `path` consist of `path`s (infinite recursion) is
 not very good and should be fixed.
