commit 87ed6365e47fea2112d62a32f234f63eab8a6b19

    builder/virt-index-validate: try to cleanup in any occasion
    
    Always close the file (ignoring its result) after a parsing, and cleanup
    the parse_context object before any exit().
    
    This eases the debugging of memory issues in the actual parser.
