The ICE got fixed with r251433.  Since then the error is:
pr77522.C: In instantiation of ‘void f(T) [with T = int]’:
pr77522.C:8:7:   required from here
pr77522.C:3:8: error: use of ‘f(T) [with T = int]::::__a’ before
deduction of ‘auto’
   auto g = [ = f] () {};
^
pr77522.C:3:12: error: invalid initialization of non-const reference of type
‘auto&’ from an rvalue of type ‘’
   auto g = [ = f] () {};
^

Paolo, will you check the testcase in and remove 8 Regression?

In trunk we don't ICE anymore on this, I think we can safely remove the 8
Regression marker and commit a testcase. I'm wondering however why when
initialize_reference calls error_at the input_location is at the open square
bracket. Well, just a curiosity, at some point expr itself will have its own
usable location.
