Important notice: this bug occurs only if part3b route's getVersion() returns 2 or greater.

This patch solves the problem.

I'm having the same issue... It affects (at least) version 1.10

Although this patch does fix the problem related to the Chain route, the problem might be more related to modifying the Request_Http object. Actually changing the Request_Http object to pass along some modifications seems to be a bit misplaced or am I missing something important??

Using the actual request object in a route (version 2) seems feasible, but it might not be when dealing with chained routes. Any thoughts?

The provided patch solves the problem. The chain class is calling $request->setPathInfo($path) in case that it finds match, but it doesn't do it when not (places where return false; is calles).

I am providing test where it is shown how evaluating route A is influencing route B evaluation.

Output of this test is:

1. test matches, path info=/xxx/too
B route matches: yes
2. test fails which is correct, path info=xxx/too
A route matches: no
3. test fails which is wrong, reason is that the route A has change path info=too
B route matches: no
finished.
