Yes, this is known and unfixable, it's a gcc bug: https://github.com/JuliaLang/julia/issues/28325 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64243

Do you need this functionality on Win64? If so, the only workaround I am aware of is to compile libcxxwrap-julia using MSVC (which is easy, thanks to CMake, see the appveyor script of libcxxwrap-julia).
