Hi, My build is failing on message.cpp with: ../../../libs/locale/src/shared/message.cpp(439): error: invalid type conversion: "const wchar_t *" to "const char *" static_cast<char const *>(p), ^ detected during: [...] caused by code like: ================= template<typename CharType> struct hash_function { size_t operator()(message_key<CharType> const &msg) const { pj_winberger_hash::state_type state = pj_winberger_hash::initial_state; CharType const *p = msg.context(); if(*p != 0) { CharType const *e = p; while(*e) e++; state = pj_winberger_hash::update_state(state, static_cast<char const *>(p), static_cast<char const *>(e)); state = pj_winberger_hash::update_state(state,'\4'); } =================== Which looks like a legitimate error since that conversion does not seems t be covered by static_cast. This is on bot master and develop branch. The compiler is intel 16: [alainm@gurney build]$ icpc --version icpc (ICC) 16.0.0 20150815 Copyright (C) 1985-2015 Intel Corporation. All rights reserved.
