In the distant past, reshape array always showed a buffer allocation, but under some conditions it could probably re-use the buffer. (Back then, the help falsely claimed that it operates in place, but that got removed from the help long ago). Going from 1D to 2D, the size header needs to grow by 4 bytes in memory. Since the function can also be used to pad (or trim) an array, it might need a new allocation, especially if the new dimension sizes are not constants as in this case. (e.g. reshaping a 2D array with 1 element to a 1000x1000 2D array will need room for 1M points).

(I am not claiming that I know the internal details how the compiler handles all that, but it is clear that the data needs to be touched in at least some scenarios)

Ah, yes, i assumed the requested reshaping had the same amount of elements, else it'll obviously need to pad/buffer. In this case it's irrelevant though as it's some 8k elements so unless the program runs on a Vic-20 it'll fit. 🙂

This ofttimes-fact really saved my bacon once upon a very (very) long time ago.  To use a Ben-ism, here's more of that particular "Sea Story".

(But heed what altenbach wrote -- the ability to operate in-place isn't guaranteed nor even always *possible*)
