When using "gcc -O2 -Wall -Werror" to compile libsepol, the following
error happens:
services.c: In function 'constraint_expr_eval_reason':
services.c:820:2: error: 'answer_list' may be used uninitialized in this
function [-Werror=maybe-uninitialized]
free(answer_list);
^
Indeed, because of a goto statement in constraint_expr_eval_reason
function, "free(answer_list)" can be called before answer_list has been
initialized.
Fix this error by moving the definition of answer_list to the beginning
of constraint_expr_eval_reason.
