Segmentation faults with large arrays

MODULE test2;
  VAR string: ARRAY 0FFFFFFFH OF CHAR; i: INTEGER;
BEGIN
  FOR i := 0 TO LEN(string)-1 DO END;
END test2.

The problem is artithmetic overflow of pointer arithmetic in gc.c(scratch_alloc).

[Spivoxity]

As a workaround, try allocating from the heap:

VAR string: POINTER TO ARRAY OF CHAR;
NEW(string, 0FFFFFFFFH);

Fixed in 3.0.3
