Question

我正在尝试在Windows上格式化json值，其中包括：

json::value root;
root["uid"] = "uid";

但是，当它试图释放时，应用程序崩溃了。

== [发布什么：]

== 代码的一部分在这里：

// @param key is not null-terminated.
Value& Value::resolveReference(char const* key, char const* cend)
{
  JSON_ASSERT_MESSAGE(
      type_ == nullValue || type_ == objectValue,
      "in Json::Value::resolveReference(key, end): requires objectValue");
  if (type_ == nullValue)
    *this = Value(objectValue);
  CZString actualKey(
      key, static_cast<unsigned>(cend-key), CZString::duplicateOnCopy);
  ObjectValues::iterator it = value_.map_->lower_bound(actualKey);
  if (it != value_.map_->end() && (*it).first == actualKey)
    return (*it).second;

  ObjectValues::value_type defaultValue(actualKey, nullSingleton());
  it = value_.map_->insert(it, defaultValue);
  Value& value = (*it).second;
  return value;
}

任何人都可以给出一些暗示吗？谢谢！
