Thanks for the complete stack-trace. This seems to fail in a test that validates the expected exception is thrown. The test line contains `check_exception("The argument index value is too large for the number of arguments supplied", SV("{:"));` The call to `failed_throw` seems to indicate there's no catch handler found.

So I also start to suspect an issue in the unwinder. I'm also not sure how to debug that. Since the tests passes on other platforms including platforms using sanitizer I'm happy to keep the suppression on Zorg.
