(the pull request came in end of 2016, and luajit is STILL broken for 52bit addressing for example). my take is that luajit is basically broken on 64bit as it makes major assumptions on the VALUE of an address - if the kernel were to remap elsewhere in virtual memory in certain ways it'd still be broken if we just used basic raw pointers. adding the documentation at least kind of helps... but it's still a major design error. we've worked around it in git by now. > cu Andreas > -- > `What a good friend you are to him, Dr. Maturin.
