I can reproduce.

Looks like std::vswprintf is incompatible. I sent an inquiry to mingw list, but I suspect this is a gcc issue.

 Yes: you must use MinGW-w64 trunk for GCC >= 4.8. This requirement allowed everyone to enjoy std::to_string. Thank your friendly libstdc++ maintainers.

any patch known to make it work?
Comment 6 Alon Bar-Lev (RETIRED) gentoo-dev 2013-11-29 20:00:12 UTC 
Should be fixed with latest mingw64-runtime.
Please reopen if not.
