In cmd/regulator.c an error occurs with GCC 9.2.1 if CONFIG_ERRNO_STR is not defined: cmd/regulator.c: In function ‘failure’: cmd/regulator.c:20:2: error: ‘%s’ directive argument is null [-Werror=format-overflow=] 20 | printf("Error: %d (%s)\n", ret, errno_str(ret)); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ In function ‘constraint’, inlined from ‘constraint’ at cmd/regulator.c:111:12: cmd/regulator.c:115:3: error: ‘%s’ directive argument is null [-Werror=format-overflow=] 115 | printf(" %s (err: %d)\n", errno_str(val), val); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ errno_str() should return a valid string instead of NULL if CONFIG_ERRNO_STR is not defined.
