            Bug ID: 24213
           Summary: Unwinding fails when linking object file produced by
                    rustc
           Product: lld
           Version: unspecified
          Hardware: Macintosh
                OS: MacOS X
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs
          Assignee: unassignedbugs at nondot.org

    Classification: Unclassified

Full repro is here: https://github.com/tamird/rust_lld, but you'll need a
working rust compiler and might need to massage build.sh for your system.

TL;DR unwinding fails with `fatal runtime error: Could not unwind stack, error
= 5`.

Here's the symbol table diff between what `ld` produces vs `lld`:
