…40367) Meet code dump when using single stream multi table load: ``` SUMMARY: AddressSanitizer: heap-buffer-overflow /root/doris/be/src/io/fs/multi_table_pipe.cpp:99:22 in doris::io::MultiTablePipe::dispatch(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char>> const&, char const*, unsigned long, doris::Status (doris::io::KafkaConsumerPipe::*)(char const*, unsigned long)) ``` 1. It is hard to guaranteed that msg is a C-style string ending in '\0' character. If not, it may cause the core dump to access memory out of bounds. 2. It is not need to calculate the length of msg twice. Therefore, deleting the logic that using strlen to calculate the length of msg.
