+null pointer dereference in tcg_emit_op
+
+I am insert a custom  tcg helper function in i386_tr_insn_start for trace the instructions.
+
+most of time the qemu runed ok ,but when execute some special software  will lead to crash.
+
+
+the below is the insert code:
+=======================================================================================
+
+ 8514 static void i386_tr_insn_start(DisasContextBase *dcbase, CPUState *cpu)
+ 8515 {
+ 8516     DisasContext *dc = container_of(dcbase, DisasContext, base);
+ 8517     TCGv_ptr ptr= tcg_const_ptr((void*)cpu); // inserted hepler code
+ 8518     gen_helper_mad_exec(ptr);// insert helper code
+ 8519     tcg_gen_insn_start(dc->base.pc_next, dc->cc_op);
+ 8520 }
+======================================================================================
+
+below is the callstack
