Function EnsureS3InitializedWithSigpipeHandler

r/src/filesystem.cpp:301–309

Initialize S3 with the SIGPIPE handler enabled. Without it, stale connections in the SDK's connection pool can trigger SIGPIPE during Aws::ShutdownAPI(), which causes R's signal handler to longjmp out of the teardown and segfault (GH-50009, GH-32026).

// which causes R's signal handler to longjmp out of the teardown and segfault

  options.install_sigpipe_handler = true;
  auto status = fs::InitializeS3(options);
  // InitializeS3 returns Invalid if already initialized - that's fine
  if (!status.ok() && !fs::IsS3Initialized()) {
    StopIfNotOk(status);
