It appears to be old.  An xterm selection is placed on the Windows clipboard in 
CF_UNICODETEXT format.  'getclip' can deal with this, 'getclip -u' and 'getclip 
-d' cannot; they always request CF_TEXT (i.e., ANSI) format and assume they get a 
buffer of data.  But the formats don't match and there's no data supplied.  That's 
why the segfault occurs.

I've committed a patch to the cygutils git repository that fixes the segfault:
https://cygwin.com/git/?p=cygwin-apps/cygutils.git;a=commit;h=3e94e050af7ad4ac84d12c18e9408e4c4f34cb56

The fix will be part of an upcoming build of cygutils, 1.4.16-9, hopefully in the 
next few days.  Beyond that, the limitation in formats with "-u" and "-d" will be 
relaxed later on.
Regards,

..mark
