This patch fixes the "Server provided a broken/invalid certificate"

messages (at least up to 4k attributes).

I'll tie it into the build with the incoming Cryptlib update, but I want
it to be a separate commit since it fixes a long-standing issue while the
rest of the update commit will just unbreak new broken bits.
