A tiny patch for a giant function. This kind of looks right, based on
some other examples in the function, but it's hard to say for sure
since this one function (X509_verify_cert; is that important?) has
about a dozen different exit points which free or don't free any
number of variables, stacks,
While you're there, all alloc error paths need to free sktmp and
whatever else is done at `end:'. But I am not sure the
X509_get_pubkey_parameters() needs to be performed upon error as well,
despite the code disagreeing with me.
I mean, I would investigate, but my glasses just turned dark on me.
