grsecurity segfault

[shamgar]

I've been working on building a set of ACLs for one of my machines,
but no matter what I put in the acl, enabling it gives me a segfault, and
a dump in my logs as included below.

I'm running crypto-sources, 2.4.19-r7, and the latest unmasked
gradm (1.2.1) both of which are rather old as far as versions go.
(The patch to 2.4.19, not the kernel obviously). Has anyone else
seen this, or have anything for me to try? Depending on the
response from gerk I'll probably just patch in the crypto stuff I need
by hand to vanilla-sources if not, but if I can do it more easily than
that it'd be nice.
