[PARSE BUG]: Trailing return declarations broken on pure-virtual methods

[kdkavanagh]

Problem description

Pure-virtual methods with trailing return types fail to be parsed. Works with non-pure-virtual trailing returns and pure-virtual methods w/ regular return signatures

C++ code that can't be parsed correctly (please double-check that https://robotpy.github.io/cxxheaderparser/ has the same error)

class Clazz {
 public:
 virtual auto getTelemetryMarker() const -> std::string const& = 0;
 
}

Isn't that an invalid function declaration? I'd expect a trailing return type declaration to use the auto keyword, per https://en.cppreference.com/w/cpp/language/function.html

Sorry, yes you're right. Just a bad manually typed example instead of copying out of my codebase. Will fix the description - still errors regardless
