> Hi, i built 2.0.8 and error disappeared. could you tell where in manual i can read about donwgrading packages

If SBCL is in your main profile, you could downgrade it with:

--8<---------------cut here---------------start------------->8---
guix package --roll-back
guix package --upgrade --do-not-upgrade=sbcl
--8<---------------cut here---------------end--------------->8---

Or you could create an environment with "guix time-machine":

--8<---------------cut here---------------start------------->8---
guix time-machine --commit 21e79225352a5e78aa329b6cd213eb553862c363 -- environment --ad-hoc sbcl
--8<---------------cut here---------------end--------------->8---

Here 21e79225352a5e78aa329b6cd213eb553862c363 is the commit just before
the patch upgrading SBCL to 2.0.9.
