I just built Wireshark after performing a svn update. If Wireshark is
the active application (has focus) and you hit <alt><ctl><del> to lock
the computer, when you unlock or cancel you will find the Wireshark
application has crashed. Seems like the work to change the keyboard
input to automatically echo to the display filter window is causing
the crash. Note that you don't have to have any files loaded, just
launch Wireshark, make sure it's the primary application with focus,
then press <alt><ctl><del> on the keyboard.

Cannot reproduce this on my machine - with the same lib versions.
Don't know why this crashes on your machine.
isprint() doesn't have a limited input range so it shouldn't crash on
this call - and on my machine it doesn't do so even with the value 65513.
Did you tried a distclean which might help in curious cases ...
