That's basically already in the code:
while ((l = ERR_get_error_line_data((const char **) &file, &line,
(const char **) &data, &flags)) != 0)
log it ...
but that does not generate any output. Even if I add
the line you suggested there's no extra output
(to make sure there would be something I also added
an BIO_fprintf() and that output is shown, so it's not
a problem with the BIO).
I guess I have to figure out how to use wireshark for this.
