Sanity checking asn.1_encode patch

[Tony Rodriguez]

I am new to kerberos.   How can I sanity test that recursion within 
asn.1_encode stops after 31? Does kerberos have any command line 
utilities to test asn.1_encode?  If so, what are they and which 
parameters must I pass? If not, does someone have example code that I 
can compile to test the recursion level logic works as expected?

Thanks,
