Ok, that was easy to install and get the coverage, and now I see the error.

Except I still don't know the gcc plugins well enough to fix it at the
plugin level. And the gcc docs only talk about TREE_STATIC() for
functions, not for variables. Apparently variables should use
DECL_THIS_EXTERN or DECL_THIS_STATIC according to the docs I find, but
..

Removing the __latent_entropy marker obviously fixes things.
