The Mach-o library which causes the crash

Steps to reproduce:

1. Check out LLVM SHA-1 54c522420347e58aa7bae1892cf5c5672b57c875 from
https://github.com/llvm/llvm-project/;
2. Build llvm-objdump
(https://github.com/llvm/llvm-project/tree/master/llvm/tools/llvm-objdump) with
msvc 32-bit;
3. Run it using the attached file with options: -macho --exports-trie
libexpat-osx

It crashes with:
