Showing values of parameters packs in gdb

How can one see the values of a parameter pack in a variadic function in gdb?

Sample code (VariadicDebug.cpp):

template <typename... Ts> int Do(int a, Ts... ts)
{
  // Add breakpoint here. a can be seen using 'print a' but how to show ts???
  return a;
}

int main(int argc, char **argv)
{
  return Do(0, "Hello world!", 88.9);
}

Compile with

g++ --std=c++11 -O0 -g VariadicDebug.cpp

And run gdb:

$ gdb ./a.exe

(gdb) break VariadicDebug.cpp:4

Breakpoint 1, Do<char const*, double> (a=0) at VariadicDebug.cpp:4

(gdb) info args
a = 0

As you can see: It only gives the value for a not for ts.
