The issue is that RTLD_DEFAULT uses the DL_LOOKUP_RETURN_NEWEST flag while RTLD_NEXT doesn't. Fix the RTLD_NEXT branch to use DL_LOOKUP_RETURN_NEWEST. Note: the new behavior matches FreeBSD rtld. Future sanitizers will not need to add versioned interceptors like https://reviews.llvm.org/D96348 Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
