No, `s->traced` depends only on the command line flags and will be true if and only if `--trace-symbol=foo` is passed for a given symbol `foo`.   It can be true or false independently of everything else going on here.

I'm not sure what you mean by "and then again".  I only see a single call to `printTraceSymbolUndefined` in this function.
