segfaults on M1 Mac for arch arm64e #31

I build dsdump on M1 Mac myself. It works fine for x86_64 arch library, but fails for arm64e arch library

  1. first run
dsdump -sc /usr/libexec/sharingd
Multiple arches found: [ x86_64 | arm64e ]
Use --arches (-a) (or ARCH env var) to specify arch

so add -a x86_64, fine

dsdump -sc /usr/libexec/sharingd -a x86_64
