Well, it blows up even sooner on a Solaris/SPARC system at work, because
it tries to dereference an uninitialized (and misaligned) pointer.

A lot of the problem is, I suspect, that we're not checking the return
values of a bunch of the routines, which will return error codes for
ASN.1 BER dissection errors.

I'm working on that one; hopefully, it'll let me get to the other
problem (or fix the other problem).
