       3     We expect 3 DATASEC records: one for each of .data, .rodata and .bss.
       4     .rodata: the consts; c,e,my_cstruct
       5     .bss:    a,b,bigarr
       6     .data:   d
       7  
       8     The type IDs of the variables placed in each section are not deterministic
       9     so we cannot check them.
