Thanks for posting your /var/log/syslog which contained the faulting address 0x410f1c. I see now what the issue is:
Looks like this can be fixed by using vxorps instead of vpxor.

Could you please download these two files:
To the o/build/bootstrap/ directory, and then re-run the build?

I am stuck and cant move.
After downloading files and run build again It did not helped and failed with huge blue output again.
I dont post it here thou.

Don't know if it's the same issue but I also get an illegal instruction exception in ar.com while running make from the repository:
ARCHIVE.a o//libc/stubs/stubs.a
Illegal instruction (core dumped)
archive failed: o/build/bootstrap/ar.com rcsD o//libc/stubs/stubs.a libc/stubs/ …
make: *** No rule to make target 'o//libc/stubs/stubs.a', needed by 'o//ape'. Stop.
(Ubuntu 20.04, AMD CPU, running inside a LXC environment)
dmesg has the following message:
ar.com[445797] trap invalid opcode ip:407488 sp:7ffecd16c568 error:0 in ar.com[400000+9000]
Digging deeper:
$ echo 0x7 > /proc/self/coredump_filter
$ make

...
$ objdump -d core|grep 407488

This makes sense. This is an avx2 instruction and the CPU I'm testing on only supports up to avx.
Trying with gdb and the other version of ar.com above gets me the following backtrace:

Hi @jart - I think you've done great and novel work here :) I am super excited to try this project!
Just FYI, I have the same problem on Debian with an old i5 laptop (Lenovo T420). Same with the versions of ar.com you provided. Looks like same issue as @tankf33der
Seemingly my system compiles the code fine but fails at archiving the object-code with an "illegal instruction" error message.
I suspect the missing AVX2-support is at blame here.
A question: With which assumptions is cosmopolitan built? (I'm sure it can be found in the code/built-scripts, but I haven't found it..). It sounds plausible that there is an assumption about AVX2 support that just needs to go somewhere?
