I did, but probably not in an optimal way.

It was some weeks ago, so I don't remember exactly, but I think I used
the pkix.asn definition shipped with libtasn1 together with a dummy
It'd probably better to fuzz the parser with a small asn1
definition exposing some of the interesting/complex features of asn1
and a smaller than 1kb input file. However I'm not really into asn1
definitions, so I was unable to create something alike quickly.
