Yes, because the current implementation uses the information about number of them:
```
template <typename ELFT> void ELFDumper<ELFT>::printGnuHashTable() {
....
Elf_Sym_Range Syms = dynamic_symbols();
unsigned NumSyms = std::distance(Syms.begin(), Syms.end());
if (!NumSyms)
reportError(createError("No dynamic symbol section"), ObjF->getFileName());
W.printHexList("Values", GnuHashTable->values(NumSyms));
}
```
Such implementation implies, that if I add a one more - a garbage will be dumped:
```
Values: [0x8, 0x9, 0xA, 0xB, 0x6FFFFEF5]
```
I think it is a bug. We should either error out or don't print garbage values and warn this case instead.
I am going to fix this.
