    # Pck.A is an array that embeds elements with variable size so compilers will
    # emit DWARF attributes such as DW_AT_byte_stride to tell GDB how to fetch
    # individual elements.  Array stride is also a way to describe packed arrays:

    # that elements have variable size.  Fortunately, type resolution of array
    # elements happens only when processing individual elements (i.e. the resolved
    # array type is still associated to the dynamic element type), so the following
    # is supposed to work.
