+      # causing the debug-only assertion (FOLLY_SAFE_DCHECK at line 234)
+      # to fail with SIGABRT.
+      # Since F14SetFallback.h is a header-only template compiled by any
+      # target that includes it, we define NDEBUG for ALL targets to set
+      # folly::kIsDebug=false, disabling the assertion. This matches the
+      # behavior of Release/Production builds which already define NDEBUG.
