That's a jack2 problem. jack2 is supposed to be a drop-in
replacement for jack-audio-connection-kit... but the .pc file for
jack-audio-connection-kit has -lpthread and the one for jack2 does
not. This is only an issue for fluidsynth when building with jack2
support. Adding -lpthread to fluidsynth is one way to fix it, but the
correct fix is going to be to add it to jack2's .pc file.

So far there's been no mention of jack in this thread... maybe try
rebuilding fluidsynth without jack support at all, see if that affects
vlc's segfaulting (doubt it, but worth a try).
