In a role-of-role context a callout binding can cause the error mentioned
in the title although the source code does not have an explicit reference
to the non-public role.
This is witnessed by test1122_layeredTeams8() where the callout
  void k() -> void k()
is implemented using a call to the internal bridge method
  _OT$R1$private$k(R1<@theTeam>)

That first parameter is generated and actually is a baseclass reference
that shouldn't be checked for this kind of access issue.
