signals2 fails to compile under Intel Parallel Composer XE

[anonymous]

I'm trying to compile the following file:

class Order {};

class Foo
{
  signal<void(Order*)> beforeOrder;

  void test(Order* o)
  {
    beforeOrder(o);
  }
};

int main(int argc, char* argv[])
{
  Order o;
  Foo foo;

	return 0;
}

Here's the compiler output I'm getting:

Same problem compiling on Scientific Linux, Boost Version 1.55.0

Intel® C++ Studio XE for Linux* 2013 SP1 $ icpc -v icpc version 14.0.3 (gcc version 4.7.1 compatibility)

This compiles fine under gcc version 4.7.1
