Repeatable crash of client on use of alias

[vinoveritas]

it is possible while creating an alias that is less then 128 char long that contain variables, which would push it past 128 chars. the alias gets created and on use with a variable that pushes it out or range it will make the client crash so we need to put a check in the client if an alias after inserting all variables are to long or not.

Could you provide me an example via a PM?  I can't make this happen but get a "command too long" error.
