Ever since the introduction of SIP, system-level debugging tools like LLDB have 
worked very poorly for me, even on self-built executables.  I don't see a 
difference in its behavior on 10.11 vs. 10.12 though.  I can run it on `curl` 
from Homebrew, but not `python`; my guess being that Python is trying to 
dlopen() some SIP-protected thing whereas `curl` is loading only things from 
Homebrew?

If it's a VM, then system integrity is less of a concern; have you tried just 
blanket disabling SIP to see if that improves the situation?  I've had some 
luck with other tools (dtrace, mostly) working in that configuration.  (I had 
to totally disable SIP though, disabling one flag at a time didn't work.)
