Bug ID: 42214
Summary: non-const lvalue reference to type is actually
allowed?
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: C++
Assignee: unassignedclangb...@nondot.org
Reporter: zhong...@pku.org.cn
CC: blitzrak...@gmail.com, dgre...@apple.com,

My clang is 9.0.0, and the code is:
template<class ...V>
struct VariableList {
void ConnectAllToAll(VariableList<>& params = VariableList<>()) {
}
};
clang rejects it:
<source>:3:39: error: non-const lvalue reference to type 'VariableList<>'
cannot bind to a temporary of type 'VariableList<>'
void ConnectAllToAll(VariableList<>& params = VariableList<>()) {
^ ~~~~~~~~~~~~~~~~
<source>:3:39: note: passing argument to parameter 'params' here
1 error generated.
Compiler returned: 1
However, icc, gcc, and msvc all accept the code. non-const lvalue reference to
type is actually allowed?
