Well since I've no idea what that vtrCertStatus structure does any
analysis is somewhat limited. However because you presumably have to use
the (unsigned char **) case and because I'd guess its an internal
pointer that looks questionable. Do you really want the call to modify
.b_data after it has been made?
Reading the FAQ might help. Particularly the bits about how to get
further info if a function fails and how to use the ASN1 functions.
