‎Hi,

As you may have seen in thread "‎Re: [boost] [Boost-bugs] Fwd: [Boost C++ Libraries] #11211: Fusion example no longer compiles"‎.

We also have a really serious issue in Boost 1.58 with Fusion on any compiler with constexpr support (that is when C++11 is enabled). The macro BOOST_FUSION_DEFINE_STRUCT fails to compile with non constant expression compatible types.

This is a terrible issue, because most of the people using spirit uses BOOST_FUSION_DEFINE_STRUCT. 

We already merged a bugfix on master, we however have to check that the others DEFINE macros aren't affected.

Cheers,

Strictly from a Boost user's perspective, the Context (and therefore 
Coroutine, ASIO) build problem is a pretty serious one. gcc-4.8.x / 
C++11 is a pretty mainstream configuration nowadays. At the very least, 
the publishing of a patch file on boost.org as has been done in the past 
would be appreciated in order to enable building with this compiler 
configuration.
