Guile sudden problems on Debian bullseye

Hi all,

all of a sudden my TeXmacs 1.99.13 stopped working today.
If I run it from cli, it gives me the error that I report below.

Apparently Guile 1.8 stopped working. I'm trying to recompile it
but no version gets it through. The Guile 1.8 provided
from the git (guile-msvc-1.8.8) hangs on compiling too.

Any suggestions?

I have an up to date debian bullseye amd64.

Have you a TeXmacs deb-src package ready to recompile locally?
(I see there are now a lot of different binary deb packages,
thus you may have the src to prepare them, I guess)

Thanks a lot

Giorgio
