    + Improve error message for unsupported inner types and declarations
    + Don't allow "va_list" as return-type or type of fields [#884]
    + Check before accessing "name" of parent_symbol which might be null

    + Always bail if there are semantic errors
    + Fix base-access check for compact classes
    + Improve detection of recursive struct declarations [#902]
    + Inline allocated arrays require length or initializer [#903]

  - genie: Fix parser's inner state when a struct is declared after a class
  - girparser: Apply explicitly given ctype metadata attributes on callables
  - testrunner: Invalid tests and therefore expected failures must return 1
