Hi,

Here's a short example:

slayoo at skua:~$ clang++ --version

Target: x86_64-pc-linux-gnu
Thread model: posix



slayoo at skua:~$ cat test.cpp 
#include <utility>
struct c
{
  static void f(
    std::pair<const double*, const int*> = std::pair<const double*, const
int*>(0,0)
  ) {}
};



slayoo at skua:~$ clang++ -c test.cpp 
test.cpp:5:79: error: expected ')'
    std::pair<const double*, const int*> = std::pair<const double*, const
int*>(0,0)
                                                                              ^
test.cpp:4:16: note: to match this '('
  static void f(
               ^
test.cpp:5:67: error: expected '>'
    std::pair<const double*, const int*> = std::pair<const double*, const
int*>(0,0)
                                                                  ^
