The issue seems to be in the Twig/Environment::addGlobal function. This now checks if "layout" in the example above is in the $this->globals array which it isn't, and you get into this if statement because runtimeInitialized gets set because loadTemplate is called.
So you seem to have to change the above code from:
$app->before(function () use ($app) {
$app['twig']->addGlobal('layout', $app['twig']->loadTemplate('layout.twig'));
});to
$app->before(function () use ($app) {
$app['twig']->addGlobal('layout', null);
$app['twig']->addGlobal('layout', $app['twig']->loadTemplate('layout.twig'));
});So, get the layout global in the array so you can update it later. Is this valid, or something else amiss here?
Hi There! Did you ever figure out what was going on here?

This no longer seems to work. Is this deprecated now in Silex/Twig? I get:
"LogicException: Unable to add global "layout" as the runtime or the extensions have already been initialized."
