atomic/detail/gcc-sparcv9.hpp: constexpr constructor with non-empty body

[smr@…]

The named file has several examples of a constexpr constructor that has a non-empty body. I'm far from a C++ expert but a little googling suggests this is not legal C++11.

This issue was first reported as issue #723115 in Debian's Bug Tracking System. I can't report the actual URL because trac thinks it is spam. Look at bugs [dot] debian [dot] org.

The sparc code for boost::atomic seems to be incorrect. Supercollider [1] failed to build on sparc with the following message:

/usr/include/boost/atomic/detail/gcc-sparcv9.hpp: In constructor 'constexpr boost::atomics::detail::base_atomic<T, void, 1u, Sign>::base_atomic(const value_type&)':
