Description Markus Schorn

2010-09-01 11:28:25 EDT

When mixing method-templates with global functions for a user-defined operator the overload resolution fails. Here is an example:

struct S {
  int s;
};
struct X {
  template<typename T> S* operator+(T t) const {return 0;}
};
int* operator+(const X&, int *) {return 0;}

void test() {
   X x;
   (x + 1)->s;
}

testcase + fix

The patch also cleans up the computation of the implied object type for method calls.
