Issue confirmed.

IMHO: AutoIt should throw AutoIt error something like:
Array ReDim has not set number of subscripts.

Both ReDim throw a syntax error in SciTe. What do you expect more?

Replying to Andreik:

AutoIt3 shouldn't hard crash.

I understand and it should be treated more elegant as a runtime error. My point was if you write invalid code then it's a high chance to get bad or unexpected behavior. By the way, are you allowed to compile from SciTe if you have syntax errors?
