Initialization of `t8_vtk_data_field_t` hangs for Julia versions older than `v1.9`.

[jmark]

The following code hangs for Julia versions older than v1.9.

  vtk_data = t8_vtk_data_field_t(
    T8_VTK_SCALAR,
    NTuple{8192, Cchar}(rpad("Element data\0", 8192, ' ')),
    pointer(some_element_data),
  )

This problem has been fixed for Julia v1.9 and newer. Thus, it is highly recommended to use Julia v1.9 or newer.

In the future, this workaround will be dropped when Julia v1.9 (or newer) is more widely established in the community.

Do you know why it is hanging? Also, why creating a tuple with 8k entries and not just a plain array - maybe that would fix things?

[jmark]

Already went through many possible roads and tried to fix it. Had a discussion in Julia Slack as well. The problem is not related to the tuple. It has something to do with processing the wrapped struct and some extremely deeply nested macro recursions in older versions of Julia.. Besides, normal arrays do not work for struct members. Tried that already.

Ah, this is a constructor call and not a regular function call, I see.
