# Proposed changes
Issue Number: close #13939
## Problem summary
```cpp
inline auto get_json_token(const std::string_view& path_string) {
#ifdef USE_LIBCPP
return boost::tokenizer<boost::escaped_list_separator<char>>(
std::string(path_string),
boost::escaped_list_separator<char>("\\", ".", "\""));
#else
return boost::tokenizer<boost::escaped_list_separator<char>>(
path_string, boost::escaped_list_separator<char>("\\", ".",
"\""));
#endif
}
```
When we use BE (built with **libc++**), in function `inline auto
get_json_token(const std::string_view& path_string)`, we use a temporary
`std::string` object to create `boost::tokenizer`. As a consequence, the result
of `std::vector<std::string> paths(tok.begin(), tok.end())`
([be/src/exprs/json_functions.cpp#329](https://github.com/apache/doris/blob/master/be/src/exprs/json_functions.cpp#L329))
is wrong.
