Thanks, it looks rather tricky ! I run the test suite again and got a
few failures when building guix :

The error seems to come from :

--8<---------------cut here---------------start------------->8---
ERROR: In procedure setvbuf:
ERROR: Wrong type (expecting exact integer): line
builder for `/tmp/guix-tests/store/c12sgw3ip2pmwbrmz9yld5ndfq3ck5x3-profile.drv' failed with exit code 1
--8<---------------cut here---------------end--------------->8---

I attached the report, and will have a clother look tomorrow.
