Hopefully the stack trace is informative even though some stuff is missing. They are missing because the debug symbols are missing for this version of LLVM:

$ dpkg -S /usr/lib/x86_64-linux-gnu/libLLVM-7.so.1
libllvm7:amd64: /usr/lib/x86_64-linux-gnu/libLLVM-7.so.1
$ apt-cache policy libllvm7       
libllvm7:
  Installed: 1:7.0.1~+rc2-2
  Candidate: 1:7.0.1~+rc2-2
  Version table:
 *** 1:7.0.1~+rc2-2 500
        500 http://deb.debian.org/debian unstable/main amd64 Packages
        100 /var/lib/dpkg/status
$ apt-cache policy libllvm7-dbgsym
libllvm7-dbgsym:
  Installed: (none)
  Candidate: 1:7-8
  Version table:
     1:7-8 500
        500 http://deb.debian.org/debian-debug unstable-debug/main amd64 Packages

Would you be able to re-enable them Sylvestre?
