            Bug ID: 96884
           Summary: Missing diagnostics when applying the member operator
                    on this in class template
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: anders.granlund.0 at gmail dot com
  Target Milestone: ---

Program (main.cpp):

  template<typename T>
  class V
  {
      int *a;
      void f()
      {
          this.a = 0;
      }
  };

  int main()
  {
  }

Compilation command line:

  g++ -std=c++17 -pedantic-errors main.cpp

Observed behaviour:

  No compilation errors.

Expected behaviour:

  Compilation error about incorrectly trying to use the member operator (.)
instead of (->) on the this keyword.

Note:

  clang++ gives the expected error message.
