Hi Boost Experts
Below is the code that is causing crash on solaris:
entity::VecObj getData(const message::Message& msg) { entity::VecObj odfs; util::MyString keyStr;
keyStr = _T("Test msg"); for(size_t i=2; msg.hasKey(keyStr) ; ++i) { util::MyString mdfAlias = msg.value(keyStr); entity::VecObj ret = storage::byAlias(mdfAlias); if(ret.size()) odfs.push_back(ret[0]);
keyStr = _T("Test msg") + util::convert(util::getString(i)) + _T("]");
} if(!odfs.size()) throw util::Exception(util::ERROR_MDFNOTFOUND, util::ERROR_MDFNOTFOUND_STR);
return odfs; }
template std::string getString(const T& val) { std::string res(""); try { res = boost::lexical_cast(val); } catch(bad_lexical_cast&) { }
return res; }
Below is the stack trace corresponding to it.

I am wondering how can this crash can happen for a very simple case of converting from unsigned to string using lexical cast. Any help would be highly appreciated.
I've noticed _T macros. Are you using wxWidgets? This macro is used if you want to have code working for unicode and byte character strings. Maby you use unicode characters? I don't know if it's the problem but if you use unicode, std::string won't work. wxString will. Regards, Adam
