Compilation error on Mac OS X and Composer XE beta 2015

Hi,

I m trying to compile a very simple threaded app using the Intel Composer XE beta 2015. The program compiles just fine on a Linux platform but fails on latest Mac OS X:

Sample program: threaded_cpp

#include <cmath>
#include <iostream>
#include <thread>
#include <vector>

using namespace std;

void f(int start, int end, float* input, float* output){
    for(int i=start; i != end; ++i){
        output = sqrt(sin(input)*sin(input+cos(input)*cos(input)));
    }
}


int main(){
    const int data_size = 100000000;

    float* input = new float[data_size];
    float* output = new float[data_size];

    for(int i=0; i<data_size; ++i){
        input = i;
    }

    const int num_threads = std::thread::hardware_concurrency();

    std::vector<std::thread> threads;

    const int block_size = data_size/num_threads;

    int start = 0;
    for (int i=0; i < (num_threads-1); ++i){
        threads.push_back(std::thread(f, start, start+block_size, input, output));
        start = start + block_size;
    }

    f(start, data_size, input, output);

    for(auto& thread : threads){
        thread.join();
    }

    delete[] input;
    delete[] output;
    
}

compile command:  icpc -std=c++11 -no-vec threaded_for.cpp -o threaded_for

I reproduced the issue. I've filed internal tracker.
