I have a customer that getting the following error when trying to

Platform: Solaris 9

Compiler: SunPro 5.9
Build: Multithreaded-Debug-shared

Error Message:

"include/map", line 206: Error: second is not a member of RWCString.
"GOCC_GuiPref.cc", line 93:     Where: While instantiating
"std::map<RWCString, GOCC_WinPref*, std::less<RWCString>,
std::allocator<RWCString>>::operator[](const RWCString&)".

This doesn't look like a valid specialization of std::map. The
template is declared like so:

  template <class Key, class T,
            class Compare = less<Key>,
            class Allocator = allocator<pair<const Key, T> > >
  class map;

I.e., the type of map from RWCString to GOCC_WinPref* is:

  map<RWCString, GOCC_WinPref*,
      less<RWCString>,
      allocator<pair<const RWCString, GOCC_WinPref*> > >;

Note that allocator is specialized on

  pair<const RWCString, GOCC_WinPref*>.

Code:

Line 206 of Map looks like this:
    mapped_type& operator[] (const key_type &__k) {
        // note: temporary is necessary to avoid an xlC 5.0 bug (PR
#25040)
        iterator __i = insert (value_type (__k, mapped_type ())).first;
        return (*__i).second;
    }
