New Comment:
>From further investigation, although the change in behaviour of
preg_quote in Bug#47229 breaks certain elements in the Code Ignighter
Framework, it has more to do with the framework than a logical error in
preg_quote.
If anyone is interested, the default settings of Code Igniter 1.7.1
will
cause URI.php line 189 to fault and return a false negative. I will
alert them of this.

This was due the fix for Bug#47229.
But does this breaking your code?
