I'm getting a segfault in the renderer process on both win64 and lnx64.  I've not yet isolated a minimal test case but the interrupt always occurs at _NewFromUtf8_.

> Program received signal SIGSEGV, Segmentation fault.

This is on the latest release 1.2.2.

atom/renderer/atom_renderer_client.cc
v8::Handle<v8::Context> context, content::RenderFrame* render_frame) {
  
  
  if (!render_frame->IsMainFrame() && !IsDevToolsExtension(render_frame))
    return;
  
  bool first_time = node_bindings_->uv_env() == nullptr;
  
  if (first_time) {
    node_bindings_->Initialize();
    node_bindings_->PrepareMessageLoop();
  }
  
  node::Environment* env = node_bindings_->CreateEnvironment(context);
  
  atom_bindings_->BindTo(env->isolate(), env->process_object());
  AddRenderBindings(env->isolate(), env->process_object(),
                    preferences_manager_.get());
  
  node_bindings_->LoadEnvironment(env);
  if (first_time) {
    
    node_bindings_->set_uv_env(env);
    
    node_bindings_->RunMessageLoop();
  }
}
