Whenever a script tries to pass too many parameters through string concatenation, it might crash OpenTTD in some revisions:

The following script creates a string of 7 parameters, and then tries to concatenate three copies of it.
The squirrel checker will not pick up this programming error, because it thinks it's fine.

The failure then happens within openTTD itself, as an assertion failure in strings_func.h

Tested in 1.3.0 beta 64-bit windows, crash happens.
Also tested in trunk. r24976, crash happens.
Interestingly: This crash does NOT happen in stable 1.2.3 64-bit windows.
