I tried using the nested_coding branch for the eap-aka-sim submodule, since that branch had its latest commit last year while passing all tests on github. However, I could not get it working -- it results in a segfault and I have attached the logs (*segfault.log).

  Use the "master" branch.  The current tests which are failing are not relevant to SIM.

I noticed in the comments for the send Start-Request section that the version could be negotiated here, but when I put the SIM-Algo-Version attribute in that section instead of in the Challenge-Request section, that didn't cause the version negotiation step to happen.

  To be honest, I'm not overly familiar with SIM.  And like most things in v4, it's unreleased.  It might change at any moment.  It might work (or not).  Much of it is undocumented.

  If it works, great.  If not... we're happy to accept patches for code and/or documentation.
