Seen on Ubuntu 18.04 with
gcc version 7.5.0 (Ubuntu 7.5.0-3ubuntu1~18.04)
giving:
rsa-ltm.c: In function ‘ltm_rsa_private_calculate’:
rsa-ltm.c:135:9: error: variable ‘where’ set but not used [-Werror=unused-but-set-variable]
int where = 0; /* Ignore the set-but-unused warning from this */
^~~~~
rsa-ltm.c: In function ‘gen_p’:
rsa-ltm.c:482:9: error: variable ‘where’ set but not used [-Werror=unused-but-set-variable]
int where = 0; /* Ignore the set-but-unused warning from this */
