If you're freeing the memory you just realloc'ed within the callback, then
where is your data stored? You only need to free() 'memory' if you malloc'ed
it beforehand. Nowhere in the code snippet you gave do you show that you
alloced any heap to be stored at 'memory', nor do you show that you alloced
any heap to be used as the initial memory block in 'memory->data'. Nor do you
show where you free 'memory->data' after your transfer is complete.

It's hard to guess at what your code is actually doing. Why not show
us the actual code?
