[Bug c++/33990] bug in lookup of member template conversion operator for pointer to member functions

2009-10-04 Thread ylalym at gmail dot com 


--- Comment #3 from ylalym at gmail dot com  2009-10-04 15:33 ---
(In reply to comment #0)
There is a makeshift.

File a.cpp
#include 

const class nullptr_t
{
public:
  template operator T*() const { return 0; }
  template operator T C::*() const { return 0; }

  // void (C::*pmf)() = nullptr;// Ok
  // if (nullptr == pmf) {} // Ok
  template bool operator == (C (T::*p)()) const
{ return  p == 0; }

  private:
void operator&() const;

// const int n = 0;
// if (nullptr == n) {} // Error
bool operator == (long) const;
}
nullptr = {};

struct C
{
  void func();
};

int main(void)
{
  void (C::*pmf)() = nullptr;
  if (nullptr == pmf) {printf("Ok\n");}

  // If there are sentences - send 
  // if (pmf == nullptr) {printf("Ok\n");} // Error
}

> g++ a.cpp
> ./a.out
Ok

Without PCH errors aren't present.
> all preprocessed headers to build the PCH

#include 

It is enough one header for error origin.
