OK. I have to treat non-enveloped data also. I was looking for a clean
way to check this fact. Maybe what I'm looking for is something along
the lines of dumpasn.c which would tell at least if the data was in ASN
format.

Possibly the buffer I use needs to be bigger than the data in order to
leave some workspace ?

Agreed! Maybe I am going about this in the wrong way, do I need to push
and then pop before checking any meaningful attributes ? I will gladly
send all my code, the previous was an attempt to isolate and simplify.
