      We should backport this bugfix:

    Remove memory leak in fdopen (bug 31840)
    
    Deallocate the memory for the FILE structure when seeking to the end fails
    in append mode.
    
    Fixes: ea33158c96 ("Fix offset caching for streams and use it for ftell (BZ #16680)")

    libio: Test for fdopen memory leak without SEEK_END support (bug 31840)
    
    The bug report used /dev/mem, but /proc/self/mem works as well
    (if available).

      It reduces conflicts in libio/Makefile and is a useful fix to have anyway.
