When I try to compile J1B (via make in j1b/swapforth/j1b/verilator), I get the old error:

it can be easily fixed as described in #67 - there is a commit wzab@4a705b0 that can be cherry-picked to fix it.
Afterwards the J1B builds with Verilator 4.038, but an attempt to build it with 4.210 still leads to an error:

The l2-name option does not help. Inspection of files generated in obj_dir shows that t he whole class structure has changed.
