            Bug ID: 77914
           Summary: Wrong lambda definition accepted
           Product: gcc
           Version: 6.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: michele.caini at gmail dot com
  Target Milestone: ---

GCC accepts the following code, that is not valid according to the standard:

    int main() {
        auto l = []<typename>(){};
        l.operator()<void>();
    }

Flags -Wall -pedantic, no warnings, no errors.
It doesn't seem to be an extension of the compiler.
