linux unit test failure about lobster

[aardappel]

As you can see from the code just above it, it creates a cycle (a leak) on purpose consisting of 4 objects. Try printing out the return value from the GC to see what it is. Are you running any additional code besides unittest.lobster? does it do this when run by itself?

My invocation is this:

./lobster include/unittest.lobster

The output is this:

Ah, and

print(collect_garbage())

gives me 5, not 4

[aardappel]

Yeah, the output doesn't say anything.
So, that means it is somehow leaking 1 additional object. No idea how that is possible.
What you could try is removing any calls to collect_garbage(), then at the end of running it will complain about leaks, paste the contents of leaks.txt here. Mine gives:

0 = ["cycleinner", ["cycleinner", [.., ..]]]
1 = ["cycleouter", ["cycleouter", [.., .., ..], [.., ..]], ....]
2 = "cycleouter"
3 = "cycleinner"

[aardappel]

The garbage collector was removed from Lobster a while ago, so this error, whatever it was, is gone too :)
