Small code works on VS6 crash on VS2005 WHY???

This code runs without problems on VS6, but crashes on VS2005 (I've just started to use VS2005)
Please WHY??

Code:

---

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

typedef struct
{
        int iCode;
        char *pName;
        double dPrice;
} Products;

struct Node
{
        Products products;
        struct Node *pNext;
        struct Node *pPreview;
};

void AddNodeHead (struct Node **pNode)
{
        struct Node *pTemp;
        puts("Adding node");
        pTemp=malloc(sizeof(Products));
       
        puts("Done!");

        if (pTemp==NULL)
        {
                puts("Failed to allocate!");
                // Delete All
                exit(1);
        }

        pTemp->pNext=*pNode;
        pTemp->pPreview=NULL;

        if (*pNode)
                (*pNode)->pPreview=pTemp;

        *pNode=pTemp;
}


int main ( void )
{
        struct Node *pHead=NULL;
        int i;

        for (i=0;i<3;++i)
                AddNodeHead(&pHead);
        return 0;
}

---

Code:

---

struct Node *pTemp;
puts("Adding node");
pTemp=malloc(sizeof(Products));

Thank you hk_mp5kpdw.
Howerver I still can't understand what I did wrong...

The size of a Node structure is not the same as the size of a Products structure. You got undefined behavior.
You allocate too little space to hold your Node structure.

I can't believe I did such a stupied mistake.

Thank you guys!

to avoid such mistakes use the working always patter

pObj = malloc (sizeof *pObj);

Shouldn't this, dereferencing an unallocated pointer, cause undefined behavior?

Not with the use of sizeof.
Sizeof doesn't dereference the pointer, but merely evaluates the type.
