           Summary: auto deduction error in variable template lambda
           Product: gcc
           Version: 5.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: norbert.pfeiler+gcc.gnu.org/bugzilla at gmail dot com
  Target Milestone: ---

template<typename T>
auto test = [](){
    return T{};
};

int main() {
    test<int>();
}

error: use of 'test<int>' before deduction of 'auto'

Clang 3.6.2 accepts…

I’m not exactly sure this code is valid, but i can’t find much about variable
templates and lambdas.
