A fair amount of openssl code is written this way:
type v1 = NULL;
type v2 = NULL;
...do stuff...
if (error) goto escape:
normal return
escape:
if (v1) v1_free(v1);
if (v2) v2_free(v2);
...
Sometimes there's only v1, and sometimes there's up to v3,v4,v5...
I think keeping the common construction is more important than the
"needless" double-test.
