I see.

The arguments to boost::unit_test::const_string are the char const*
pointer to the string and the number of characters in the string.
(For a C style string literal "foo" this is sizeof("foo")-1 which
evaluates to 3.)

Did you really mean to pass in 1 as the number of characters?

boost::unit_test::const_string takes a C-style string literal and
provides std::string style compatible semantics (i.e. iterators,
length property, etc.).

You can think of BOOST_TEST_CASE as just a more convenient way of
invoking the constructor for boost::unit_test::test_case:
<http://user.xmission.com/~legalize/boost.test/libs/test/doc/html/test/reference/test_classes/test_case.html>

I don't see any reason why you couldn't invoke the constructor
directly.

As for how fragile all of this is -- your guess is as good as mine;
I'm not the implementor of the library.
