    In my project,there are a lot of global members. To my surprise that I found two of the global member has the overlapped memory address. For example: member a begin at address 0x00457280 and the size of a is 14D(hex) member b begin at address 0x00457380 and the size of b is 848(hex) obviously the two member overlapped! But why?I have no idea on finding out a solution! WINXP+VC6+SP6

    Don't look at me in that way!

      Can you tell more about that variables, how are declared and so on...?

        How are you verifying this?
