11624	BOOST_TEST( 0.0 == 0.0 ) fails under C++11 (GCC and Clang)	Tony Lewis <tonyelewis@…>	Raffi Enficiaud	"Thanks again for the new BOOST_TEST() tool, which looks very useful.

Unfortunately, I'm seeing strange behaviour from the following code under `g++ -std=c++11` or `clang++ -std=c++11 -stdlib=libc++` :

{{{#!cpp
#define BOOST_TEST_MODULE zero_mod

#include <boost/test/included/unit_test.hpp>

BOOST_AUTO_TEST_CASE( zero ) {
	BOOST_TEST( 0.0 == 0.0 );
}
}}}

If I compile with `-std=c++11`, then the test fails:

{{{
error: in ""zero"": check 0.0 == 0.0 has failed [0 != 0]. Absolute value exceeds tolerance [|0| > 0]
}}}

...but I compile without any `-std=[...]` option, then the test passes."	Bugs	closed	Boost 1.60.0	test	Boost 1.59.0	Problem	fixed	BOOST_TEST,zero,C++11,float
