title: cscope: Cscope error: cscope: cannot read list size from file cscope.out
body: <p><strong>Issue</strong>:
  I get the following error when I try to open a file in vim (version 7.3).</p>
  
  <p><strong>cs_read_prompt EOF: Illegal seek
  E609: Cscope error: cscope: cannot read list size from file cscope.out</strong></p>
  
  <p><strong>Description</strong>:
  I created the cscope database "cscope.out" using the command "cscope -b -R". The file ~/.vim/plugin/cscope_maps.vim contains the command "cs add cscope.out" to add the cscope database. When I try to open one of the source files, I get the error mentioned above.</p>

  <p>What could be the problem here?</p>
  
  <p>Thanks for your help.</p>
