| ## Here we simulate an object with more than ~65k sections and check how we dump it. |
| ## When an ELF object has SHN_LORESERVE (0xff00) or more sections, its e_shnum field |
| ## should be zero and sh_size of the section header at index 0 is used |
| ## to store the value. If the section name string table section index is |
| ## greater than or equal to SHN_LORESERVE, then e_shstrndx field |
| ## should have the value of SHN_XINDEX and sh_link of the section header |
| ## at index 0 is used to store the value. |
