Copy of discussion:

I ran abzsubmit this morning (which failed), and just traced down some kernel messages to it:

That's streaming_extractor_music apparently still using the old x86_64 vsyscall interface, which Debian has disabled (for security reasons) in it's 4.8 kernel. That leaves the program completely broken. That's currently just in testing/unstable, but will be part of the next stable release due out this spring.

[edit: looking into it further, Debian has reverted the change for Stretch, but will bring it back for Stretch+1. So not as urgent.]

The x64 build of essentia-extractor-v2.1_beta2 segfaults consistently for me on Debian buster (the current testing release). The 32bit one works.

This should maybe be added to the "new extractor" (or 2.1?) milestone so you don't forget about it? :)
