Segfault when using session.run with a variable on x86 Mac

Minimal example code:

use tensorflow::{Scope, Session, SessionOptions, SessionRunArgs, Variable};

fn main() {
   let mut s = Scope::new_root_scope();

   let variable = Variable::builder()
       .const_initial_value([1i64])
       .build(&mut s)
       .unwrap();

   let session = Session::new(&SessionOptions::new(), &s.graph_mut()).unwrap();
   let mut run_args = SessionRunArgs::new();
   run_args.add_target(&variable.initializer());
   session.run(&mut run_args).unwrap();
}

Running this code on my x86 Mac—with libtensorflow 2.15.0 installed via Homebrew, using Tensorflow 0.21.0 as the sole dependency in cargo.toml—leads to a segfault. The same didn't happen on a friend's x86 Linux machine, when she gave the code a test-run there. As far as we can tell, it's the variable that does it; code where no variables are interacting with session.run doesn't seem to have the same issue, on my machine.
