When parsing something like x.} the following would happen:
- Parsing "." the lexer would move to the FIELDS start condition
- Parsing } the lexer wouldn't find any <FIELDS> rule matching
- The parser would fall back to <*>. that was asserted unreachable.
The fix is to add a <FIELDS>. rule to catch bad field starts
