[BUGFIX] Fix check for stripped comments
[BUGFIX] Fix check for stripped comments

The bootstrap checks for the presence of doc comments, to avoid
problems with some bytecode caches that strip comments.

That check did not work correctly (FALSE is returned but the check
expects an empty string). In case an error is seen, the exception
cannot be thrown as well (no classloader available at that point).
That exception issue has been been fixed for another check as well.

On top of this the check for magic_quotes_gpc has been adjusted a
tiny bit.
