title: cygwin: diff.exe: error while loading shared libraries: cygsigsegv-2.dll
body: <p>I installed the latest cygwin x86-64.  I added diffutils to get the basic diff(1) linux command.   When I now run it, I get:</p>
  
  <pre><code>diff.exe: error while loading shared libraries: cygsigsegv-2.dll
  </code></pre>
  
  <p>I did a search for the dll <a href="https://cygwin.com/cgi-bin2/package-grep.cgi?grep=%20cygsigsegv-2.dll&amp;arch=x86_64" rel="nofollow">here</a>, but there are zero matches, not found.</p>
  
  <p>I then re-ran the installer and did a search in the installer search box on this dll, and nothing came up.  </p>
  
  <p>Can you please advise?</p>
