            Bug ID: 50657
           Summary: `llvm-strip -x` crashes on binary linked by lld/mac,
                    works fine on binary linked by ld64
           Product: lld
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: MachO
          Assignee: unassignedbugs at nondot.org

Link with ld64.lld, then:

% ~/src/llvm-project/out/gn/bin/llvm-strip -x  protoc
PLEASE submit a bug report to https://bugs.llvm.org/ 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 (bug 50393).
