The strncpy doesn't null terminate the string because the size is too short by one byte.
parse.c: In function ‘prepare_default_config’: parse.c:148:2: warning: ‘strncpy’ output truncated before terminating nul copying 8 bytes from a string of the same length [-Wstringop-truncation] strncpy(config->governor, "ondemand", 8); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The normal method of passing the length of the destination buffer works correctly here.
