Oh! I had no idea the --debug flag could affect build success. The original issue I
encountered was with a plain `guix pull', but in an attempt to provide the most useful
diagnostics, I tried including --debug=3. In any event, it just so happens that I
saved the output from the original pull command, which I am attaching in case it
happens to prove helpful.

As it turns out, I tried another pull just a bit earlier, which ended up succeeding;
however, I went ahead and tried running the build you suggest like this:

    $ guix pull -S 1  # broken build happened with generation 1
    $ guix build --check /gnu/store/waisnnl9nbmlbpfwbn50pif79fsdknf9-guix-packages-base.drv
    The following derivation will be built:
       /gnu/store/waisnnl9nbmlbpfwbn50pif79fsdknf9-guix-packages-base.drv
    building /gnu/store/waisnnl9nbmlbpfwbn50pif79fsdknf9-guix-packages-base.drv...

What could be causing the build to receive SIGKILL?
