librespot: Crash upon connect

I have just compiled librespot on my raspberry pi 3 (raspbian stretch), and librespot crashed after some of my connect attempts. The first 2 attempts succeeded and I was able to play music, however then when starting librespot and connecting on my iPhone librespot crashed:

Also, even when playback succeeded, I saw a lot of those warnings:
