Summary: C++0x initialization syntax doesn't work for class
members of reference type
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: [email protected]
ReportedBy: [email protected]
The following code does not compile although I expect it to:
/// BEGIN CODE ///
#include <utility>
struct S {};
struct C {
S & mc2;
S && mc3;
C( S& b, S && c ) : mc2{b}, mc3{std::move(c)} {}
};
int main() { return 0; }
/// END CODE ///
I compile it with command:
g++ test.cpp -std=c++0x -o test.exe
The output is:
test.cpp: In constructor ‘C::C(S&, S&&)’:
test.cpp:9:48: error: invalid initialization of non-const reference of type
‘S&’ from an rvalue of type ‘<brace-enclosed initializer list>’
test.cpp:9:48: error: invalid initialization of reference of type ‘S&&’ from
expression of type ‘<brace-enclosed initializer list>’
Compiler version (g++ -v):
Using built-in specs.
