Internal error causing panic when certain class static blocks are present

[clydin]

An internal check in 0.18.2 related to class downlevel info appears to be triggering and leading to a panic when --minify-syntax and --bundle are enabled with a static class block present that is empty or only contains certain expression statements. This does not occur in 0.18.1.

Really sorry about that. This case didn't have test coverage apparently. I'll push out a fix for this. Thank you very much for the report.
