It really shouldn't free the comment passed to it, as the caller allocated it, and knows how to free it if necessary; it might not even have been allocated. Make the comment argument a "const char *" to 1) allow passing string constants etc. and 2) to catch any attempts to free it in exp_pdu_open(). Make the callers free it after exp_pdu_open() returns. (Alternatively, we could have exp_pdu_open() take the file name argument and generate the comment itself, so that all code paths generate the same comment.)
