XTT*_*XTT 1 c++ string json type-conversion casablanca
我正在使用casablanca库来序列化json值.
我试图使一个转换的std :: string使用typedef std::wstring string_t和这个从wstring的字符串转换.它编译正常,但程序在执行返回行时崩溃.
std::string getString()
{
web::json::value cvalue;
/* ----- code ----- */
typedef std::wstring string_t;
string_t outputString = cvalue.serialize();
typedef std::codecvt_utf8<wchar_t> convert_type;
std::wstring_convert<convert_type, wchar_t> converter;
std::string converted_str = converter.to_bytes(outputString);
return converted_str;
}

我无法理解为什么会崩溃.下面是调用该函数的行.
std::string s = getString();

该程序free(_Ptr)在一个名为xdebug的文件中触发了一个断点.我真的不明白这里说的是什么.希望这有助于为您澄清事情.
template<class _Ty>
void __CLRCALL_OR_CDECL _DebugHeapDelete(_Ty *_Ptr)
{ // delete from the debug CRT heap even if operator delete exists
if (_Ptr != 0)
{ // worth deleting
_Ptr->~_Ty();
// delete as _NORMAL_BLOCK, not _CRT_BLOCK, since we might have
// facets allocated by normal new.
free(_Ptr);
}
}
