Bug ID: 105637
Summary: [11 Regression] Wrong overload selected in base class
Product: gcc
Version: 11.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: ted at lyncon dot se
Target Milestone: ---
This compiles fine in 11.3 but selects the non-const `BaseClass` overload in
12.1:
```
struct BaseClass {
// Commenting out this non-const function out will fix the compilation:
int baseDevice() { return 1; }
int baseDevice() const { return 2; }
};
template <class ObjectClass>
struct DerivedClass : BaseClass {};
template <class ObjectClass>
struct TopClass : DerivedClass<ObjectClass> {
public:
virtual int failsToCompile() const {
// This should choose to call the const function, but it tries to call
// the non-const version.
return BaseClass::baseDevice(); // error!
//return this->baseDevice(); // works
//return DerivedClass<ObjectClass>::baseDevice(); // works
}
};
int main() {
TopClass<int> x;
}
```
