Interesting! I think I needed an array of teststructs in the end.
Another one for the test suite?

OK. I managed to avoid the segfault by backporting get_value_type and
changing the line

  switch (TYPE_CODE (parent->type))

In c_type_of_child to 

  switch (TYPE_CODE (get_value_type(parent)))

This is still not right since the pointer fields which previously caused
a crash can now be expanded twice in eclipse. It seems gdb gets the type
of the child of the pointer wrong (it thinks it is still a pointer) and
allows it to be expanded again, but at least it doesn't crash!

Thanks for your assistance,

Robert
