Current Status

-LuaJIT ought to run all Lua 5.1-compatible source code just fine. -It's considered a serious bug if the VM crashes or produces unexpected -results — please report this. -

-Known incompatibilities and issues in LuaJIT 2.0: -

-There are some differences in implementation-defined behavior. -These either have a good reason, are arbitrary design choices -or are due to quirks in the VM. The latter cases may get fixed if a -demonstrable need is shown. -
-The Lua debug API is missing a couple of features (return -hooks for non-Lua functions) and shows slightly different behavior -in LuaJIT (no per-coroutine hooks, no tail call counting). -
-Currently some out-of-memory errors from on-trace code are not -handled correctly. The error may fall through an on-trace -pcall or it may be passed on to the function set with -lua_atpanic on x64. This issue will be fixed with the new -garbage collector. -
