Analyzer fuzz crash: invalid super syntax in const constructor #38550

Open MichaelRFairhurst opened 4 years ago

class D {
  const D(): super."";
}

Without const, this causes #38041, so these are likely related.

Yes, this issue has the same underlaying issue as #38041 - SuperConstructorInvocation with null as argumentList.
