This is a known issue with the pre-2.0 ABI on Linux and was one of the 
motivations for the new ABI.  It began to appear with fairly recent ld-linux.so 
and has become deterministic with subsequent releases.  You will see this on 
*any* libobjc2 release with *any* version of clang on *any* system that uses 
glibc’s run-time linker.  

I don’t know if it appears on Android with the bionic run-time linker, it does 
not appear on any other platform that I’ve tested.
