Aha, found a more complete testcase here:

http://stackoverflow.com/questions/21690154/clang-3-5-constexpr-inconsistency-errors-when-using-double-but-not-int

This is not a Clang bug: const doubles like 'boost::math::double_constants::pi'
can't be used in constant expressions.

The fact that GCC accepts is a bug in GCC: http://gcc.gnu.org/PR57979
