+Subject: [PATCH] Use local variable to work around macOS compiler bug
+
+It seems that when directly passing the status, via inline condition
+etc. it triggers a compiler bug on the latest macOS ARM64 GitHub Action
+runner or Pigweed, I am not sure.
+
+Use a local variable to work around the problem.
