can we do like

#if defined(OS_WIN)
DCHECK(g_hud_typeface.Get());
#else
 .. make a typeface ..
#endif

so if it didn't happen we'll DCHECK closer to the problem?

No, unfortunately not. This is used in the browser too and NULL is OK there.

+  if (!g_hud_typeface.Get()) {
+    // This will be set pre-sandbox on Windows. On other platforms, just make
+    // something here.
+    SetHudTypeface(skia::AdoptRef(
+        SkTypeface::CreateFromName("monospace", SkTypeface::kBold)));
+  }
+#endif  // OS_WIN
+  return g_hud_typeface.Get();
+}
+
+}  // namespace ui
