... "Tcl is mostly in good shape for 64-bit platforms. The 'mostly' comes because anyone wanting any individual entity larger than 2GB (which is still a definitely humongous string!) will be in trouble. There is a major piece of clean-up still required to fix that (it's bug 219196, and as you can see it's been known about for a long long time), but I'm planning to put that off until Tcl 9.0 because it is totally incompatible with preceding API versions at the binary level on 64-bit platforms (might also require source changes, but it's the binary-level stuff that's the problem)." (Quote is from [dkf] on comp.lang.tcl) [DKF]: The remain major issue is Tcl bug #219196[https://sourceforge.net/tracker/?func=detail&aid=219196&group_id=10894&atid=110894]. As you can tell from the number and a little knowledge of SF, we've known about that particular fault/misfeature for a good few years now. ---- [[[Category Internals]]]
