Issue when assigning pointers to structure's variable

So yes, I cannot make so much sense of these outputs and I cannot say if some of them are expected and/or are known to not be working like for int***.
Would be great if you can have a look when you have some time!

The assignments and passing should work fine per se (I have a whole set of tests that do just that, up to 3D, see here: https://github.com/wlav/cppyy/blob/master/test/test_lowlevel.py#L506). The problem appears wholly with bar = ll.malloc[dtype](4), as for the first twobar thinks it's an integer array and for the last one a long array (hence the type mismatch; the long most obviously b/c it represents the pointer).

Must be something obvious missing as the generated malloc funcs aren't any different than the ones I use in the test ...

The problem is the reshaping. For the result to know that it is of length 4, the ll.malloc call fixes up the size after the fact, by reshaping to (4,). And that turns each multi-dim array into a 1D array. That's an easy fix, at least for the int** case, which seems to have the proper shape before the reshaping (is in repo; change is in ll.py, so easy to apply locally). The int*** case, however, does not. Still digging for that one.

Okay, done. I had to refactor the executors same way as the converters to support any-dimensional pointer returns.

Wow that was super efficient! Thanks a lot!
So yes, in my case I wasn't using ll.malloc, but I was doing the same mistake with the reshaping.

Released with cppyy 2.2.0 and its dependencies.
