            Bug ID: 86305
           Summary: g++ segfaults when compiling template member function
                    that calls destructor
           Product: gcc
           Version: 8.0.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: zhonghao at pku dot org.cn
  Target Milestone: ---

The code is as follow:

template <typename T>
struct
C1
{
 ~C1() {}
 void foo1();
};

template<typename T>
void C1<T>::foo1() {
 C1::~C1();
}

void foo1() {
 C1<int> x;
 x.foo1();
}

clang++ accepts the code, but g++ rejects it:

code0.c.cpp: In instantiation of 'void C1<T>::foo1() [with T = int]':
code0.c.cpp:16:9:   required from here
code0.c.cpp:11:9: error: no matching function for call to 'C1<int>::~C1()'
  C1::~C1();
  ~~~~~~~^~
code0.c.cpp:5:2: note: candidate: 'C1<T>::~C1() [with T = int]'
  ~C1() {}
  ^
code0.c.cpp:5:2: note:   candidate expects 1 argument, 0 provided


A previous version of clang++ produces similar error
