+// Issue #66530: We would ICE if someone compiled with `-o /dev/null`,
+// because we would try to generate auxiliary files in `/dev/` (which
+// at least the OS X file system rejects).
+//
+// An attempt to `-o` into a directory we cannot write into should indeed
+// be an error; but not an ICE.
+//
+// However, some folks run tests as root, which can write `/dev/` and end
+// up clobbering `/dev/null`. Instead we'll use a non-existent path, which
+// also used to ICE, but even root can't magically write there.
+
+// compile-flags: -o /does-not-exist/output
+
+// The error-pattern check occurs *before* normalization, and the error patterns
+// are wildly different between build environments. So this is a cop-out (and we
+// rely on the checking of the normalized stderr output as our actual
+// "verification" of the diagnostic).
+
+// error-pattern: error
+
+// On Mac OS X, we get an error like the below
+// normalize-stderr-test "failed to write bytecode to /does-not-exist/output.non_ice_error_on_worker_io_fail.*" -> "io error modifying /does-not-exist/"
+
+// On Linux, we get an error like the below
+// normalize-stderr-test "couldn't create a temp dir.*" -> "io error modifying /does-not-exist/"
+
+// ignore-windows - this is a unix-specific test
+// ignore-emscripten - the file-system issues do not replicate here
+// ignore-wasm - the file-system issues do not replicate here
+// ignore-arm - the file-system issues do not replicate here, at least on armhf-gnu
