@EvilSOB:

you are right! There must be a strange error with the sizeof() Macro.

This version runs correctly:
Code:
function main()
{
	int n = sizeof(short);
	short *var1 = sys_malloc(10 * n), *var2;
	// or using constants: short *var1 = sys_malloc(10 * 2), *var2;
	
	int i;
	for (i=0; i<10; i++)
		var1[i] = i;
	
	var2 = var1; // correct
	
	printf("%d", var1[6]);
	printf("%d", var2[6]); // Expected result "6"
}


where this version turns var2 into a pointer to a short pointer:

Code:
short *var1 = sys_malloc(10 * sizeof(short)), *var2;
