Any idea @fzyzcjy about sanitizers here? also @jwinarske please note that our test dart VM is not actual VM we just mimic the behaviour of the actual VM. Nonetheless, looks like most of these errors are from running that test here https://github.com/sunshine-protocol/allo-isolate/blob/master/tests/containers.rs#L243-L245 and not sure where we spawn new threads or using channels?

[jwinarske]

I think an improvement would be to use Dart SDK for the tests. It's a matter of fetching the stable flutter SDK and adding it to the path. I'll look into a PR for this next week.

[fzyzcjy]

Not sure, maybe we should create a minimal reproducible sample, probably without allo-isolate and with only a few lines of Rust code, first?

[shekohex]

Hello @jwinarske, did you find any new updates on that?

[jwinarske]

@shekohex I'm busy with something else right now. I'll get back to it at some point in the near future.
