Hmm, the problem is due to arg_new_temp()?
Yes.
Maybe add as tcg_temp_[ebb]_[reset|flush]() helper so we can reuse,
like in tcg_func_start() and plugin_gen_inject()?
Ah, right. I had a memory of solving this same problem once, but couldn't remember where,
or if it was on a branch somewhere. Good idea.
