How correctly to use Parallel Inspector?

[max-divulskiy]

Good afternoon.

Can You prompting why Parallel Inspector shows memory leak in a following example?

[bash]#include "stdafx.h"
#include 
#include 
#include 

class SimpleSum 
{
	float* my_a;

public:

	float sum;
	
	void operator( )( const tbb::blocked_range& r )
	{
		float *a = my_a;

		for( size_t i=r.begin(); i!=r.end( ); ++i )
			sum += a;
	}

	SimpleSum( SimpleSum& x, tbb::split ) : my_a(x.my_a), sum(0) {}

	void join( const SimpleSum& y )
	{
		sum += y.sum;
	}
	
	SimpleSum(float a[] ) :
	my_a	(a), 
	sum		(0)
	{
	}
};

int _tmain(int argc, _TCHAR* argv[])
{
	UINT	Size = 1000;
	float*	Mass = (float*) _aligned_malloc(Size * sizeof(float), 16 );

	for (UINT i = 0; i < Size; i++)
	{
		Mass = (float) i;
	}

	SimpleSum sf( Mass );

	parallel_reduce( tbb::blocked_range(0, Size), sf );

	printf("Result: %f\n", sf.sum);

	_aligned_free( Mass );

	return 0;
}
