Unable to view large CRLs in DB

[Jim]

I wrote a program to view CRLs in the DB (similar to crlutil) but it
doesn't work in all situations.  I'm aware that there was a problem
with previous versions of NSS that didn't support CRLs greater than
64KB.  I'm using NSS-3.3.2 and NSPR-4.1.2 to compile my program. 
Listed below is the source.  I have a CRL that is 118KB and the
program fails to find the CRL in the DB.  (I'm also testing with a CRL
that is 41KB and it works just fine.)  I'm using the certutil command
that comes with NSS-3.3.2 to build the DB and the crlutil command to
import the CRL.  (The crlutil also fails to find the CRL in the DB
after it imports it.)  The problem occurs when I check crlList->first;
this is NULL even though SEC_LookupCrls returns a valid crlList.

int main(int argc, char* argv[])
{
    CERTCertDBHandle    *crlDBHandle    = NULL;
    CERTCrlHeadNode     *crlList        = NULL;
    CERTCrlNode         *crlNode        = NULL;
    CERTCrl             *crl            = NULL;

    NSS_Init(configDir);
    crlDBHandle = CERT_GetDefaultCertDB();
    SEC_LookupCrls(crlDBHandle, &crlList, SEC_CRL_TYPE);

    if (! crlList)
    {
        printf("   WARNING: No list of CRLs found to do lookups\n");
    }
    if (! crlList->first)
    {
        /* PROGRAM FAILS HERE */
        printf("   WARNING: List of CRLs found, but no node in the
list\n");
    }

    for (crlNode = crlList->first; crlNode; crlNode = crlNode->next)
    {
        crl = &(crlNode->crl->crl);
        listCRL(crl);
    }
    return 0;
}

Any help would be greatly appreciated.
