[cfe-dev] Clang fails to compile

[kamlesh kumar via cfe-dev]

Hi Devs,
Consider below testcase

$cat test.cpp

struct A
{
struct B
{
double m = 0.;
};
void f(double d, const B &b = B{}) {}
};

==============

clang fails fails to compile above tescase ,while it goes smooth with
icc and msvc.
is clang doing right?
