Hi,
Per Coverity.
make_ruledef function can dereference a NULL pointer (actions),
if "ev_qual" is provided and "actions" does not exist.
The comment there is contradictory: " /* these could be nulls */ "
Because if "ev_qual" is not null, "actions" cannot be either.
Solution proposed merely as a learning experience.
regards,
Ranier Vilela
