Iterating over two-dimensional arrays

emptytheory

Why does the following program run into an error ("Unknown type: 4"),

array small[2]
array big[3]
for i = 0 to len(small) loop
    small[i] = big
repeat

counter = 0
for i = 0 to len(small) loop
    for j = 0 to len(big) loop
        small[i][j] = 1
        counter += 1
        print(counter, ": ", small, "\n")
        update()
        sleep(1)
    repeat
repeat

while this one does not?:

array small[2]
array big[3]
for i = 0 to len(big) loop
    big[i] = small
repeat

counter = 0
for i = 0 to len(big) loop
    for j = 0 to len(small) loop
        big[i][j] = 1
        counter += 1
        print(counter, ": ", big, "\n")
        update()
        sleep(1)
    repeat
repeat

Is there a line number where it breaks?

Am I missing something or is it identical except for array variable names?

@MikeDX It gets to line 13 two times, but I get the error the third time.

The difference is between (i) a short array with long arrays as elements, and (ii) a long array with short arrays as elements. The first kind gets the error message.

This is definitely a bug and I shall go file it in our issue tracker. Thanks for pointing it out (and the code!)
