I just modified both testLocalNamespaceAlias and
testDeclareUsingNamespace to use InsertIntoDUChain (I had to remove
EnvironmentManager::init() from the test initialization to avoid an
assert about double init() call).

The problem persists. Running both tests gives different results than
running them separately.
