It seems the problem spawn from recursive call (impact method) on lib/procedo/procedure.rb line 581:

def impact(casting, global, updater)
    proc = Procedo::CompiledProcedure[self.name].new(casting, global, updater)
    before = proc.casting
    proc.impact!
    after = proc.casting
    return after
end
