Follow-up Comment #5, bug #39041 (project octave):
I was able to obtain a backtrace for

As expected, Octave gets it right that the return type for this should be a
cell array. It calls do_single_type_concat<Cell> correctly. The probablem
seems to be that the struct is held as an octave_value. When the code tries
to get the underlying object using octave_value_extract<Cell> this results in
calling the method cell_value() on the octave_value object. But I don't see
an overload in ov-struct.h for the cell_value routine.
