Vittorio Zecca <zeccav at gmail dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |zeccav at gmail dot com --- Comment #4 from Vittorio Zecca <zeccav at gmail dot com> --- I still have the same bug in g++ 5.2.0 in the following: #include <map> #include <string> using namespace std; struct CData { struct CItem { string m_str1; }; map<string, CItem> m_map; std::string m_strDFName; int m_nDFMsgTimeout; }; CData func() { CData data; data.m_map["Test"].m_str1 = "Data"; return data; } class B : public CData { public: B() : CData(func()) { std::string s; map<string, CItem>::iterator it = m_map.begin(); for (; it != m_map.end(); it++) // loops past the end { s += it->second.m_str1 + it->first;; } } }; int main() { B b1; return 0; }
