cxxsim: error: ‘p_sub_2e_s’ was not declared in this scope

[cestrauss]

Consider the following test case:

from amaranth import Signal, Module
from amaranth.sim import Simulator

m = Module()
sub = Module()
m.submodules.sub = sub
s = Signal()
t = Signal()
sub.d.comb += t.eq(s)

sim = Simulator(m, engine="cxxsim")
sim.run()

When run, it fails for me with:

sim.cc: In member function ‘virtual void cxxrtl_design::p_top::reset()’:
sim.cc:38:2: error: ‘p_sub_2e_s’ was not declared in this scope
  p_sub_2e_s = value<1>{0u};
  ^~~~~~~~~~

Full log attached.

Should be fixed by YosysHQ/yosys#3127.
