[boost] Boost::lexical_cast<> under llvm 3.4

Hi, Has anyone tried boost::lexical_cast<> on clang++ based on llvm/clang++ 3.4? Or is it too early to use 3.4? Couldn't find any recent references to problems with lexical_cast (except from Mar 16, 2013 and older, but boost_1_54_0 does have that fix in it). No problems with llvm/clang++ 3.3, but on a test machine under 3.4 it produces the errors shown in below file lexical_cast-error.txt. The files are also at https://github.com/goedman/clang11-spirit-qi , in the Boost_lexical_cast directory. As far as I can see, all other parts of a spirit::qi project does build, the error occurs in a small print utility where lexical_cast<> is used.. Rob J. Goedman goedman@icloud.com
