<pre>I ran into this while writing tests for a patch I'm working on. It happens
without my patch too though:
thakis@MBP llvm-project % cat share.s
.globl _foo, _bar, _baz
.weak_definition _bar
_foo:
retq
_bar:
_baz:
retq
.subsections_via_symbols
thakis@MBP llvm-project % cat share2.s
.globl _main, _foo, _bar
.weak_definition _bar
_bar:
retq
_main:
callq _foo
callq _bar
thakis@MBP llvm-project % out/gn/bin/clang++ share.s share2.s -isysroot $(xcrun
-show-sdk-path) -fuse-ld=lld
ld64.lld: warning: Option `-no_deduplicate' is not yet implemented. Stay
tuned...
thakis@MBP llvm-project % ./a.out
zsh: bus error ./a.out
Works fine with ld64.
(I didn't see this in any "actual" code, so probably not super high priority.)</pre>
