I'm moving this call further up, before calling bench_set_keys() and
without the "if". This gets rid of the rest of Valgrind's complaints
except for a couple of "Conditional jump or move depends on
uninitialised value(s)" that may be .
For example, KRB4 has this in top of set_key():
if (saved_salt->realm[0] != '\0')
...and saved_salt is just a pointer to the memory that bench.c allocated
and then freed.
