Bug ID: 48260
Summary: Unexpected "address of overloaded function 'f' is
ambiguous" error for overloaded variadic template
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: C++11
Assignee: unassignedclangb...@nondot.org
Reporter: dpho...@gmail.com
CC: blitzrak...@gmail.com, dgre...@apple.com,
erik.pilking...@gmail.com, llvm-bugs@lists.llvm.org,
richard-l...@metafoo.co.uk
The following program compiles successfully on GCC and MSVC:
template<typename X, typename... Y>
void f(X&&, Y&&...)
{
}
template<typename X>
void f(X&&, const double&)
{
}
int main()
{
void(*fptr)(const int&, const double&) = &f;
}
Using Clang (https://godbolt.org/z/5jE18P) we get:
<source>:13:46: error: address of overloaded function 'f' is ambiguous
void(*fptr)(const int&, const double&) = &f;
^
This seems to affect all Clang versions. Tested on trunk, 11.0.0 and 3.0.0.
