Title: set permissions as expected by composer.phar update

I'm guessing the executable permissions were removed from these files recently.

composer.json copies the following scripts (i.e., "bin": ["bin/doctrine", "bin/doctrine.php"], ) to the vendor/bin folder.

When running composer.phar update, and doctrine/orm is to be updated, composer fails because these two scripts have been chmod'd to be executable.
