[Bug c++/16883] New: Confusing error message with Boost.Spirit

[giovannibajo at libero dot it]

The preprocessed source attacched with this report causes the following error 
message when compiled with 3.4:

/cygdrive/e/spirit/boost/spirit/phoenix/composite.hpp:281: error: return-stateme
nt with a value, in function returning 'void'

The error message is totally confusing, and has nothing to do with the real 
bug, which is a missing templated operator() (or so I am told, I have not 
analyzed it). I am also told the same error message appears with 3.3.

With Comeau, the error message is: "no instance of function template 
Test_Recipe_Grammar::lazy_attribute_filter_::operator() matches the argument 
list", which is the correct problem. The full error message can be seen here:
http://rafb.net/paste/results/IiYOX564.html.

This really needs a reduction to be properly analyzed.

I get this error first:
pr16883.cc:50489: error: no match for call to `(Test_Recipe_Grammar::lazy_attribute_filter_) 
(__gnu_norm::map<uint32_t, std::pair<std::string, std::string>, std::less<uint32_t>, 
std::allocator<std::pair<const uint32_t, std::pair<std::string, std::string> > > >&, const 
std::pair<std::string, std::string>&)'

So it looks like the person is looking at the last error message rather than the first.

The reason for the error message which we output also comes from:
int f();
template <class T> T g(T *a){return f(a);}
void h(){g<void>(0);}

Which is correct because there is no f which has a return type of void. so closing as invalid.
