Bug ID: 30594
Summary: ambiguous overload of function call operator allowed
Product: clang
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: C++
Assignee: unassignedclangb...@nondot.org
Reporter: jeff.mirwa...@gmail.com
CC: dgre...@apple.com, llvm-bugs@lists.llvm.org
Classification: Unclassified
The following should be considered ambiguous:
//no error - incorrect behavior
struct B1{void operator()(){}};
struct B2{void operator()(int){}};
struct D:B1,B2{};
int main()
{
D{}();
}
without an explicit using declaration in D the overloads provided by the two
bases should be considered ambiguous as in the analogous case for member
functions.
//error: member 'f' found in multiple base classes of different types - correct
//behavior
struct B1{void f(){}};
struct B2{void f(int){}};
struct D:B1,B2{};
int main()
{
D{}.f();
}
