Description

It seems, VC++ 2010 have bug with global references to arrays.
Got strange results with this code with VC++ 2010 - compiles, but gives wrong results.
Tested with C++Builder 2010 and GCC 4.2.4 (on linux) - works just fine.


#include <stdio.h>

// Simple data
int IntArr[10] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};

// Pointer to simple data
int (*IntArrPtr)[10] = &IntArr;

// Reference #1 to pointed data
int (&IntArrRef1)[10] = *IntArrPtr;

int main(int argc, const char* argv[])
{
	// Reference #2 to pointed data
	int (&IntArrRef2)[10] = *IntArrPtr;

	printf("Data from IntArrRef1: ");
	for (int i = 0; i < 10; i++)
	{
		printf(" %d ", IntArrRef1[i]);
	}
	printf("\r\n");

	printf("Data from IntArrRef2: ");
	for (int i = 0; i < 10; i++)
	{
		printf(" %d ", IntArrRef2[i]);
	}
	printf("\r\n");
	
	return 0;
}
