LD_PRELOAD="/usr/lib/x86_64-linux-gnu/libtcmalloc.so.4"
this caused all types of problems, I finally removed it and got guix to load.
nix has the same error.
What I found is that libunwind is needed and if install that via guix I
was able to preload that libunwind from guix and get things to work.
that leads me to belive that libunwind should be part of the prereqs in the bookstrap in guile-boostrap and that led me to the source of that module that is so complex i got scared.
let me know what you think.
