This library has no ABI guarantees upstream, which is painful to deal with. I've figured out what they messed up and hopefully put things back like they should be with the correct ABI. Thanks for the headsup, sorry it took a bit longer to get to it, I've filed an upstream MR to restore the ABI there, to avoid it in future.
