Boost.Test failing to compare std::basic_string<char8_t> strings

Hi Boost.Users,

I’m using Boost.Test from Boost 1.72.0 and I’m getting a failure when I perform the following test:

auto string_1 = u8”value”s;
auto string_2 = u8”value”s;
BOOST_TEST(string_1 == string_2);

However, the problem goes away when I change the test line to:

BOOST_TEST((string_1 == string_2));

What is the reason why Boost.Test is failing without the double parentheses?

Kind regards,
Leo
