            Bug ID: 34996
           Summary: Possible incorrect message in file
                    "libcxx/include/list" line 484
           Product: libc++
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: All Bugs

While experimenting with a CodeSonar plugin we develop, we noticed a potential
bug in file "libcxx/include/list" line 484 (method

pointer operator->() const
                       "Attempted to dereference a non-dereferenceable
list::iterator"); //HERE

Shouldn't the string message be "Attempted to dereference a non-dereferenceable
list::const_iterator" instead of the current one? The operation is for a
const_iterator (being in class __list_const_iterator). Moreover, for operator*
the message also mentions a "const_" iterator.
