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.
