Sorry, looks like my manual word wrapping lost a character:

This now reads correctly with OpenSSL.  So the real error here was that
sometimes OpenSSL accepts unwrapped base64, and sometimes not, but
asn1parse never accepts it.

The second certificate seems garbaged at the 4th RDN of the issuerName.
The Base64 edition might have added or deleted some characters.

More information, the original certificates supplied by the end user
had unwrapped base64 blocks, lines 2,500 long.  I wrapped them for
email.  

If I try the asn1parse command on the wrapped certificates, they now
attempt to parse, the OK is fine, the bad one now gives an error
message from asn1parse:

Error in encoding
20236:error:0D07209B:asn1 encoding routines:ASN1_get_object:too
long:crypto\asn1\asn1_lib.c:91:

and error:09091064:PEM routines:PEM_read_bio_ex:bad base64 decode
from PEM_read_bio_X509.  

The RFC says 'Parsers MAY handle other line sizes' but it would be good
if OpenSSL gave a 'PEM line too long' error rather than no error.  I'll
change my library code to check for line ending in the base64 to give
the user a polite message.  

Now the only problem is what is asn1 decoding unhappy with?
