As the whhole econf_file structure is freed by econf_free(file) at the end of blkid_read_config, econf_file structure cannot be defined as static and initialized only once. The econf_free() is not robust enough and keeps a pointer to the garbage after the first call. And if /etc/blkid.conf does not exist, it is called second time.
