           Summary: gcc interprets C++0x initialization construct as
                    function declaration‏‏
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: zeratul976@hotmail.com


For the following code:

struct S
{
    int a;
    float b;
};
struct T
{
    T(S s) {}
};
int main()
{
    T t(S{1, 0.1}); // ERROR HERE
}

gcc 4.6 trunk gives the following errors (with the --std=c++0x option):

decl.cpp: In function 'int main()':
decl.cpp:14:10: error: expected ')' before '{' token
decl.cpp:14:10: error: a function-definition is not allowed here before '{'
token
decl.cpp:14:18: error: expected primary-expression before ')' token
decl.cpp:14:18: error: expected ';' before ')' token

It seems gcc is interpreting the statement as a function declaration.

I think this is valid C++0x.
