None of the libraries in

These files contain "freeaddrinfo":
WS_30513\k5sprt32.dll      10/06/2009 00:19     32,768 1.6.3.16
WS_30666\k5sprt32.dll      10/06/2009 00:19     32,768 1.6.3.16
WS_30513\krb5_32.dll      10/06/2009 00:19    720,896 1.6.3.16
WS_30666\krb5_32.dll      10/06/2009 00:19    720,896 1.6.3.16
WS_30513\libwireshark.dll 11/10/2009 19:47 27,926,528 1.3.1.30513
WS_30666\libwireshark.dll 22/10/2009 20:17 28,043,776 1.3.1.30666
WS_30666\libgio-2.0-0.dll 07/10/2009 15:11    670,569 

should be Wireshark-specific - they should be used by  TShark as well.

If the Windows run-time linker resolves symbols at call time rather than at
library-load time, it could be that, for whatever reason, TShark somehow never
ends up calling freeaddrinfo().

Presumably

doesn't apply to libwireshark.dll, unless the fc command is incapable of
correctly handling what I presume are files of different sizes; k5sprt32.dll
and krb5_32.dll have the same size and mod time, so they probably have the same
contents - and we might not be calling any of the routines therein that use
freeaddrinfo(), if there are any.

At least from a quick look at the libgio source, it *does* - at least in GLib
2.22.4 - use freeaddrinfo().
