Bug ID: 34702
Summary: Address of variadic template function leads to type
deduction failure
Product: clang
Version: 5.0
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: -New Bugs
Assignee: unassignedclangb...@nondot.org
Reporter: m...@ookypooky.com
CC: llvm-bugs@lists.llvm.org
This code:
--
template<typename... Ts>
void f (Ts... vs, int y);
auto p = &(f<>);
--
Fails to compile as follows:
--
$ clang++ -std=c++17 clang.cpp
clang.cpp:4:12: error: address of overloaded function 'f' does not match
required type 'void (int)'
auto p = &(f<>);
^~~
clang.cpp:2:6: note: candidate template ignored: failed template argument
deduction
void f (Ts... vs, int y);
^
1 error generated.

The code compiles fine in g++, FWIW. I don't see why it would be illegal, and
if it is illegal then the error message could do with being improved!
