Comment (by iay):

 I've had no response from upstream, so although I do worry a bit that
 SoftHSM2 is becoming defunct, it seems like we should dig into this and
 see if we can cherry-pick those changes.

 The examples you put on the libp11 ticket are a little difficult to
 reconcile with what I have installed, and in particular I'd like to
 reproduce the issue without having to be in the process of recompiling
 some other package, which is what I think you were doing there.

 Would it be possible for you to come up with a reproduction of the issue
 with just what one can install directly from MacPorts today, plus any
 command-line actions are necessary?

 I realise your example required multiple openssl engines and that you were
 using a Yubikey HSM for your second one; I don't have one of those but I
 do have a Nitrokey HSM hard token that I think I can substitute.
