Array of structs breaks when adding new structs.

vinicity

I have a program that looks something like this:

var segments = []
segments[0] = [
    [.a = {200, 300}, .b = {240, 100}],
    [.a = {240, 100}, .b = {540, 100}],
    [.a = {540, 100}, .b = {240, 100}],
    // ..and a lot more statements like these...
]

// Then a little later I do this:
segments[0][len(segments[0])] = [.a = {840, 100}, .b = {620, 400}]
print(len(segments[0]))
update()
sleep(3)

// That seems to be working. But then I do it once more:
segments[0][len(segments[0])] = [.a = {140, 600}, .b = {320, 120}]
print(len(segments[0]))
update()
sleep(3)

// This time the program crashes on the last print statement!

This is the error that happens:

LINE: 43
FUNCTION: len

Unrecognised type: 1146106016

Interestingly, if I remove some of the segments from the initial segment definition I do not get the error.

My example program for this has been shared and submitted. ID: X6473MND5C

If someone knows a workaround, I would very much appreciate it.

Why not just keep track of the length in a seperate variable? Then you don’t have to use len()...

It seems broken in other ways too. For instance passing the array to str() yields a similar error.

As a workaround, I created a temp array, copied the contents of segments[0] using a loop, added the new segments, and finally copied the temp array back to segments[0] again.

Thanks for the report- A fix is in the works!
