Draft patch, working but failing due to another related bug

(In reply to comment #3)
[First patch]

Works for the test case, but does not regtest. The following makes more sense:
Replace "proc_pointer" by "pointer || allocatable"

 * * *

However, the test case - in the attachment - fails due to a different and in
principle unrelated reason:

find_x2 (struct __class_class_t_T & restrict this)
{
  struct tx * res;

  res.i.data = 0B;
  res = 0B;

The "res.i.data = 0" is obviously wrong: The pointer "res" should be already be
set to NULL - thus the component should in that case never be set.
