Unhandled exception (simple insertion sort func)

[jjmounes]

void insert_sort(int a[], int size)
{
	int index, position;
	for(index = 1; size - 1; index++)
	{
		position = index;
		int key = a[index];

		while(position > 0 && key < a[position-1])
		{
			a[position] = a[position-1];
			position = position - 1;
		}

		a[position] = key;

	}
}

Anyone know why this code will compile but not run? It's kicking back compiler errors that I do not fully understand.

Line 4. size - 1 not a condition.
