Re: Freeing memory when quitting Wireshark

It turns out there where several issues.  All dealing with preferences.

1 - UAT_END_FIELD not included in the uat_field_t structure. (Did not break Linux, but windows was not so kind.)
2 - In my call to prefs_register_protocol( my_proto, callback_fn) if callback_fn was NULL, wireshark/tshark would close 
correctly.  If not NULL then  wireshark  and tshark would remain in memory when closed. Again windows only.  Linux was 
OK.

I have not determined why when the callback function was included, the system failed to close.  The callback only 
updated some memory tables with the new info from the uat_new structure.

Any ideas on where to look?

Thanks as always.

When I quit a custom build of Wireshark (Win32), although the application disappears from the desktop, it remains in 
memory.

I use g_regex for a number of dissectors.  In previous versions I was using the PCRE library and did not have this 
issue.

When Wireshark quits, is there a "un-register" routing that is called in the dissector?  I am suspecting that I am not 
releasing all my memory from the compiled g_regex_new functions.

Thanks as always.
