Link with ld64.lld, then:

% ~/src/llvm-project/out/gn/bin/llvm-strip -x  protoc
PLEASE submit a bug report to <a href="https://bugs.llvm.org/">https://bugs.llvm.org/</a> and include the crash
backtrace.
Stack dump:
0.      Program arguments: /Users/thakis/src/llvm-project/out/gn/bin/llvm-strip
-x protoc
zsh: segmentation fault  ~/src/llvm-project/out/gn/bin/llvm-strip -x protoc


Works fine when linking with ld64.


Even though it's llvm-strip that's crashing, I think this is an lld bug. It
works when linking with ld64, and cctools's strip is confused by lld's output
too (<a class="bz_bug_link
