Deduction failure

[Dave Abrahams]

This program fails:

#include <boost/phoenix.hpp>
#include <boost/range/as_literal.hpp>

using namespace boost::phoenix::placeholders;
using namespace boost::phoenix;
    
int main()
{
    find(boost::as_literal("fox"), 'x')();                      // works
    find(boost::as_literal("fox"), construct<char>(arg1))('x'); // works
    find(boost::as_literal("fox"), arg1)('x');                  // compilation error
}

Took hours to work out what was going on. Nature of the beast, I suppose.

[John Fletcher <J.P.Fletcher@…>]

This compilation error does not appear with compilation for C++11 with clang 3.4 or gcc 4.8.2.

Under further investigation.

It seems that fixed on 1.54 release. ​http://melpon.org/wandbox/permlink/YinUntrMokRpqC4Z
