call to 'begin(...pull_coroutine< R > & c)' is ambiguous

[ilja.j.honkonen@…]

The test program (add t to htps) htps://github.com/nasailja/pamhd/blob/master/tests/volume_range/number_of_samples.cpp which uses htps://github.com/nasailja/pamhd/blob/master/source/volume_range.hpp which itself uses boost::coroutine stopped compiling when I upgraded Xcode. g++ --version prints:

Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 6.0 (clang-600.0.51) (based on LLVM 3.5svn)
Target: x86_64-apple-darwin13.4.0
Thread model: posix

and compile fails with:

If I comment out in file coroutine/asymmetric_coroutine.hpp the section behind #if defined(clang) everything works again. No idea if this is a user error or coroutine bug.

already fixed in branch develop ,thx
