            Bug ID: 19374
           Summary: Getting 'is not a member of' compiling error while
                    accessing class member in nested class.
           Product: clang
           Version: 3.2
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P

    # make clean all COMPILER=g++

produces no error while

    # make clean all COMPILER=clang++

outputs

h/pfsp/pivoting/best.hpp:47:20: error: 'pfsp::pivoting::best(const
std::vector<unsigned long, std::allocator<unsigned long> > &, void (*)(const
std::vector<unsigned long, std::allocator<unsigned long> > &,
pfsp::pivoting::functor<std::tuple<unsigned long, unsigned long> > *),
pfsp::eval::functor<int, std::vector<unsigned long, std::allocator<unsigned
long> >, std::tuple<unsigned long, unsigned long>, lib::array::proxy<int>,
std::vector<int, std::allocator<int> > > *)::fn::operator()(const
std::tuple<unsigned long, unsigned long> &)::fn::e' is not a member of class
'fn'


The problem seems to be that in h/pfsp/pivoting/best.hpp:47:20 I don't access
the class members using the this keyword. Adding this-> for all member access
in h/pfsp/pivoting/best.hpp and h/pfsp/pivoting/first.hpp solves the issue but
the program will not compile and strange warnings/errors pop up:
  warning: field 'e' will be initialized after field 'sol' [-Wreorder]
  warning: field 'sol' will be initialized after field 'opt' [-Wreorder]
  warning: field 'opt' will be initialized after field 'argopt' [-Wreorder]
  error: constructor for 'fn' must explicitly initialize the reference member
'sol'

('Strange' because I don't see what's the problem..)
