It is possible to cause infinite loops in LuaJIT

[ShadowNinja]

Due to what appears to be an interpreter bug, you can cause infinite loops in LuaJIT. The loops are not allowed in Lua 5.1 and 5.2. Due to the sensitive nature of this bug, and the fact that I don't know how widely this is used, I won't specify how to cause the loops. E-Mail me or contact me on freenode IRC (nick=ShadowNinja) for details, unless you think that nobody much uses this with LuaJIT. :-) As far as I know there's no way to fix this other than to sanitize the input or switch to non-JIT Lua.

Thanks for reporting this. I just sent you an email to the email on your
public github profile.

Any news on that?
