Hi,

I am working on a plugin dissector.  It works OK except when I change profiles 
Wireshark throws an exception in code in proto.c as follows:

static void
free_deregistered_field (gpointer data, gpointer user_data _U_)
{
               header_field_info *hfi = (header_field_info *) data;
               gint hf_id = hfi->id;

               g_free((char *)hfi->name);      <== The exception occurs on 
execution of this call

The hfi structure looks valid and the hfi->name does point to a character 
string.

The only thing I can see that might be wrong is that hfi->name has a data type 
of const char *

How can I determine the cause of the exception?

Thanks and regards...Paul

PS:  This is the latest git pull built with VS2013 on Windows 10 - I know I 
need to move to VS2015.
