I am the culprit.
The invocation of "guix pack -f docker" is not clear to me. So
basically, I copied/pasted the lines here [1] :-) because it works all
the time.

That said, I also find interesting the command-line and hashes comparisons:
--8<---------------cut here---------------start------------->8---
/usr/bin/gcc pi.c -o pi-debian-gcc8
docker run -v `pwd`:`pwd` -w `pwd` -ti gcc-toolchain gcc pi.c -o pi-docker
guix environment --container --ad-hoc gcc-toolchain -- gcc pi.c -o pi-guix
md5sum pi-*

1be3c1b5d1e065017e4c56f725b1a692 pi-guix
--8<---------------cut here---------------end--------------->8---
Anyway! :-)

And MPFI? ;-)
All the best,
