It is interesting that the exactly same memory blocks were allocated for the interested data and dataDesc.
It's actually pretty likely... malloc( ) often reuses a recently-freed block of the same size when it can, because this avoids heap fragmentation and improves caching.
If you really want to see what's going on, set the environment variable MallocScribble to 1 when running your program. This will cause newly allocated blocks to be filled with 0xAA and freed blocks to be filled with 0x55. It's a good way to track down references to uninitialized or freed memory.
