            Bug ID: 97303
           Summary: ICE during GIMPLE pass: *rebuild_cgraph_edges
           Product: gcc
           Version: 9.2.0
            Status: UNCONFIRMED
          Severity: normal

code causing ice

On mingw32-g++ (MinGW.org Cross-GCC Build-20200531-1) 9.2.0 cross compiler when
compiling the following snippet 

#include <stdio.h>
#include <stdlib.h>

class test0
{
public:
  virtual ~test0() {}
};

template<typename a>
class test1 : public test0
{
public:
  virtual bool doAnything() const = 0;
};

class test3_internal
{
public:
  bool depart() { return true; }
};

template<typename T>
class test3
{
public:
  typedef T element_type;

  explicit test3(T* ptr = NULL) {}
  ~test3() { depart(); }

  void reset(T* ptr = NULL) { depart(); }

private:
  void depart()
  {
    if (link_.depart())
      delete value_;
  }
  T* value_;
  test3_internal link_;
};
int main()
{
    using doesNotCompile = long unsigned int(__attribute__((stdcall))*)(void*);
    using type2 = test1<doesNotCompile>;
    // using compiles = long unsigned int(*)(void*);
    // using type2 = test1<compiles>;
    test3<const type2> test;
    test.reset();
    return 0;

}

whereas, with mingw32-g++ (MinGW.org cross-GCC-8.2.0-4) 8.2.0, it seems to
compile cleanly.
