After brew uninstall python@2 I am able to proceed.

I had gfortran10 which came with gcc. In installed gfortran (with Homebrew)
which gave me gfortran 8.2.

such a severe bug. But I am reporting it here.
If it is deemed severe I will make a trac ticket.

Note that the root system patch depends on the category

However dumps(s) will raise an exception if s is

I think you're asking about branching to products,

This is clearly needed. Maybe we need to

I've posted a patch here:

length function, etc.
