Comment (by kencu):

 clang-1100 allows it:

 {{{
 $ /usr/bin/clang -v
 Apple clang version 11.0.0 (clang-1100.0.33.17)
 Target: x86_64-apple-darwin18.7.0
 Thread model: posix
 InstalledDir:
 /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

 $ /usr/bin/clang -isysroot /Library/Developer/SDKs/MacOSX10.13.sdk -arch
 i386 -fobjc-arc writeback.m

 $ ./a.out
 2022-11-07 20:24:33.489 a.out[5851:549240] Object: <NSObject: 0x7a04c3e0>
 2022-11-07 20:24:33.490 a.out[5851:549240] Object: <NSObject: 0x7a04c3e0>
 2022-11-07 20:24:33.490 a.out[5851:549240] Object: (null)
 }}}

 so somewhere in between those.
