      - Symbol: 0xFEFEFEFE

## Case 2: Test that no warning is reported for a relocation against a symbol with index 0.
      - Offset: 0x2
        Symbol: 0
        Type:   R_X86_64_NONE
## Case 3: Test a relocation against a named section symbol that has an invalid
##         section index (larger than the number of sections).
      - Offset: 0x3
        Symbol: .sec.symbol1
        Type:   R_X86_64_NONE
## Case 4: Test a relocation against an unnamed section symbol that has an invalid
##         section index (larger than the number of sections).
      - Offset: 0x4
        Symbol: 4
        Type:   R_X86_64_NONE
## Case 4: Test a relocation against a named section symbol with a section with an invalid
##         sh_name offset that goes past the end of the section name string table.
      - Offset: 0x5
        Symbol: .sec.symbol2
        Type:   R_X86_64_NONE
## Case 5: Test a relocation against an unnamed section symbol with a section with an invalid
##         sh_name offset that goes past the end of the section name string table.
      - Offset: 0x6
        Symbol: 5
        Type:   R_X86_64_NONE
## Case 6: Test a relocation in a section that is linked to a symbol table that
##         has a section type that is neither SHT_SYMTAB nor SHT_DYNSYM.
##         In this case the code fails to find a corresponding symbol string table.
