Weird behavior C.GoString

Getting Help
1

Hi,

I am trying to link C++ shared lib to my Go program.
When I convert a C string (* char) to Go string using C.GoString it adds an extra char, in a not deterministic way.
I print the bytes of my string inside C++ shared lib and it’s correct, with \0 on the end.

//Shared lib code
for(int j = 0; j < 23; j++) {
  std::cout << std::hex <<   (int)extractor_result->error_message[j] << " " ;
}
//Go Code
fmt.Printf("%X", C.GoString(extractorResult.error_message))

Shared lib always prints:

6d 69 73 6d 61 74 63 68 65 64 20 70 61 72 65 6e 74 68 65 73 69 73 0

Golang:
printf prints:

6D69736D61746368656420706172656E74686573697308
or
6D69736D61746368656420706172656E74686573697317
or
6D69736D61746368656420706172656E74686573697307
or
6D69736D61746368656420706172656E74686573697303
and so on.

Any tips about this issue?

Thanks
