I think you should add the disassemble filter like in other places:
FlowGraphPrinter::ShouldPrint(...)

Actually, isn't the function already disassembled by
CompileParsedFunctionHelper?

Hm, yes. I guess I was missing them from my disassembly for other reasons.

+    DisassembleCode(parsed_function->function(), false);
+  }
+
   const Function& initializer = parsed_function->function();
   field.SetPrecompiledInitializer(initializer);
 }
