I suspect `out->size = strlen(byte_array)` might be the cause, as `strlen` only works with NUL terminated string and the decoded `byte_array` may contain a NUL byte (`\0`).

Try:
```c
gnutls_datum_t hex, der = { NULL, 0 };

hex.data = "3059301306072a8648ce3d020106082a8648ce3d0301070342000462d5bd3372af75fe85a040715d0f502428e07046868b0bfdfa61d731afe44f26ac333a93a9e70a81cd5a95b5bf8d13990eb741c8c38872b4a07d275a014e30cf";
hex.size = strlen(hex.data);

gnutls_hex_decode2(&hex, &der);
...
```
