#23 CSSM_CLUTIL_X509 method doesn't like empty sig structs.

[Michelle M. Manning]

CSSM_CLUTIL_X509_DuplicateSignature () doesn't like empty signature structs.

Possible fixes for this problem:

The change can be made in the clutil library in misc.c under CSSM_CLUTIL_X509_DuplicateSignature (). The function can be modified to return an empty signature struct if it receives one.

OR

The change can be made in x509v3cl in crlfield.c under x509_cl_CrlGetField(). Under the switch case case OIDasINT_X509V1CRLSignatureCStruct, you can essentially skip the call to CSSM_CLUTIL_X509_DuplicateSignature () and manually build a empty signature struct there if what's passed in is an empty signature struct.
