Dear All,

 A DEBUG Error appears when I call a delete operation in my program, eg

delete video_decoder;

I checked that it had passed all the operations in the destructor however, it can't return to my main program.

In the debug error message, it shows:

DAMAGE: after Normal block (#28) at 0x00A40060.

Do you know the reason and any solution?

Thanks

I think you overwritten a piece of memory after or before the memory you allocated, somewhere you use an uninitialised pointer, or reference a piece of memory bejond the allocated range.
In DEBUG mode, MFC (if its VC) will allocate a small extra piece of memory before and after a block of memory that is allocated with new.
When the memory is deleted, it checks if you've overwritten that piece of memory, and if so, issues an assertion.
