           Summary: ICE with lambda as default parameter of a template
                    function
           Product: gcc
           Version: 4.8.1

preprocessed buggy file

I know that my code is incorrect and shouldn't work, but ICE shouldn't happen
anyway.
I tried to play w/ SFINAE and using lambdas to do a 'concept checking' w/ a
native C++ syntax, but really soon got an ICE w/ that code

Without the *it; bit the testcase seems valid to me and compiled fine with
4.7.x.

With -O2 -funswitch-loops -fvectorize -fno-vect-const-model it started with
r178728 .
Richard, when you are back, can you please look at this?
