    nss_db: Propagate ERANGE error if parse_line fails [BZ #19837]
    
    Reproducer (needs to run as root):
    
    perl -e \
      'print "large:x:999:" . join(",", map {"user$_"} (1 .. 135))."\n"' \
      >> /etc/group
    cd /var/db
    make
    getent -s db group
    
    After the fix, the last command should list the "large" group.
    
    The magic number 135 has been chosen so that the line is shorter than
    1024 bytes, but the pointers required to encode the member array will
    cross the threshold, triggering the bug.
