Keep the actual error code and pointer-to-error-string in the scanner state, rather than pointers to the variables passed in to us. Initialize them to 0 and NULL, respectively. That way, when the actual scanner routine returns, we don't check for an error by looking at the error variable pointed to by our argument, which might not have been set by the scanner and might have stack junk in it, we look at a structure member we set to 0 before the scan.
