Hopefully this year.  What you can do in the meantime is
auto *mydata = data;
and use mydata instead of data.

Thanks. Hopefully this part of 5.0 feature will be implemented in the near
future.

4.0 had a clear
"A variable that is part of another variable (such as a field of a structure)
but is not an array element or an array section cannot appear in a map clause."
restriction, this has been lifted in 4.5 to allow the var.xyz style mapping,
but it still didn't allow general expressions as the bases of array sections.
Only 5.0 allows arbitrary expressions there.

@jakub could you mention which page and line in 4.5 spec this code violates?

It is not broken, IMHO what you are trying to do is not valid in OpenMP 4.5.

It is valid in OpenMP 5.0, but GCC doesn't implement that part yet.
