About my previous email, here is a solution i found for guix on gcp.
if I install guix from source and use that to build and install libunwind then I can use that unwind
on my system, so it appears to be a missing dep.
export LD_LIBRARY_PATH=/gnu/store/hzzr0g12n79ym28lf24y4ybqzijzqfjr-libunwind-1.6.2/lib
after that i can run guix without it crashing, sharing this.
