void Curl_infof(struct SessionHandle *data, const char *fmt, ...)
{
  if(data && data->set.verbose) {
    va_list ap;
    char print_buffer[1024 + 1];
    va_start(ap, fmt);
    vsnprintf(print_buffer, 1024, fmt, ap);
    va_end(ap);
** Curl_debug(data, CURLINFO_TEXT, print_buffer, strlen(print_buffer));
  }
}

Line 138 it marked with **
cURL version is 7.11.2

Good, using this with -d results in:

(gdb) frame 1
#1 0x403178c7 in Curl_infof (data=Variable "data" is not available.
) at sendf.c:138
138 Curl_debug(data, CURLINFO_TEXT, print_buffer, strlen(print_buffer));

Bye,
Jan
