As a matter of fact, with the released 4.6.0 I'm getting an ICE, not a silent
miscompilation for the second snippet. In mainline and in the 4_6-branch it's
already correctly rejected with something like:

...
...
48912_2.C:3:11:   in constexpr expansion of ‘f()’
48912_2.C:3:11:   in constexpr expansion of ‘f()’
48912_2.C:3:11:   in constexpr expansion of ‘f()’
48912_2.C:8:22: error: constexpr evaluation depth exceeds maximum of 512 (use
-fconstexpr-depth= to increase the maximum)

The first snippet though, the recursive function alone, is accepted in mainline
and 4_6-branch, I'm not 100% sure that's correct, probably it is but let's ask
Jason to have a look.
