Adrian Prantl 354f803ed7 Fix computeSymbolSizes SEGFAULT on invalid file ... We use llvm-symbolizer in some production systems, and we run it against all possibly related files, including some that are not ELF. We noticed that for some of those invalid files, llvm-symbolizer would crash with SEGFAULT. Here is an example of such a file. It is due to that in computeSymbolSizes, a loop uses condition for (unsigned I = 0, N = Addresses.size() - 1; I < N; ++I) { where if Addresses.size() is 0, N would overflow and causing the loop to access invalid memory. Instead of patching the loop conditions, the commit makes so that the function returns early if Addresses is empty. Validated by checking that llvm-symbolizer no longer crashes. Patch by Teng Qin!
