We don't necessarily have full control over the input tags, so it's possible that the ISRC tag contains a longer string than expected, in which case we'd write over the end of the static-size 13 byte buffer that is FLAC__StreamMetadata_CueSheet_Track::isrc. Make sure to only copy the ISRC if it's not too long, and make sure the buffer we write to is always NUL-terminated by using g_strlcpy(). CID 1324931.
