Comment (by Richard Hazlewood <boost@…>):

 Had same issue, but can confirm it does compile on the ''develop'' branch
 - not surprising because the code (''error_info_impl.hpp'') is guarded
 with:
 {{{
 #if (__GNUC__*100+__GNUC_MINOR__!=406) //workaround for g++ bug
 }}}

 We found that boost::thread fails to compile with the 1.64.0 release.\\
 Compiler call (with -d2):\\
 (Our ''user-config.jam'' points to g++4.6.4 with ''-std=c++0x'').

 {{{
 ./b2 --user-config=./user-config.jam toolset=gcc-std0x link=static -q -d2
