9188,named_slot_map.cpp fails to build in Solaris Studio 12.3,Brian Vandenberg <phantall+boost@…>,Douglas Gregor,"I'm getting an ""Overloading ambiguity error"" when building libs/signals/src/named_slot_map.cpp on or around lines 105 & 128 on the calls to `groups.erase`.

This may be related to an issue [http://www.open-std.org/jtc1/sc22/wg21/docs/lwg-unresolved.html talked about here], but that issue seems to indicate the problem would only exist in C++11.

The error goes away with the following minor edits:

{{{
-105:     groups.erase((const_group_iterator) group);
+105:     groups.erase(*(const_group_iterator) group);
-128:     if (empty(g)) groups.erase((const_group_iterator) g++);
+128:     if (empty(g)) groups.erase(*(const_group_iterator) g++);
}}}

I'm doing this work on an airgapped network, and the error is rather verbose ... but I'll give a shorted version of the error:

{{{
""libs/signals/src/named_slot_map.cpp"", line 105: Overloading ambiguity between ""std::map<A>::erase( __rw::__rw_tree_iter<B> )"" and ""std::map<A>::erase(const  boost::signals::detail::stored_group&)"".
""libs/signals/src/named_slot_map.cpp"", line 128: Overloading ambiguity between ""std::map<A>::erase( __rw::__rw_tree_iter<B> )"" and ""std::map<A>::erase(const  boost::signals::detail::stored_group&)"".
}}}
