## Case 1: There is no symbol with index 0xFEFEFEFE.
- Symbol: 0xFEFEFEFE
Type: R_X86_64_NONE
- Symbol: 0xFEFEFEFE
Type: R_X86_64_NONE
## 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 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 a section symbol that has an invalid
## sh_name offset that goes past the end of the section name string table.
- Offset: 0x4
Symbol: .sec.symbol2
Type: R_X86_64_NONE
## Case 5: 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.
