Cannot assign filter_range to any_range (gcc only)

Description

When trying to assign a filter_range to a suitable any_range, the attached source code fails to compile under g++ (v4.8.3), but does compile under clang++ (v3.4).

From the error messages I get, it seems that the error triggers when trying to use the default constructor of filter_range with Predicate = lambda and an Iterator = non-default-constructible iterator.

The defect is in the test code. A Forward Iterator, as defined by the C++ standard, must be default constructible.
