commit 33a92d56aeaadfe8dad246ae17b091e14b220e82

    [bugfix] Fix crash in basic::subs().
    
    A regression in 1.7.0 was introduced with 1b8bcb06 in function
    basic::subs_one_level(): implicitly casting *this to an ex first for
    finding *this in m and later in the function's return statement caused
    a crash in the second cast because *this was deleted in the first one.
    After all, *this was dynamically allocated in basic::subs().
    
    This bug was reported and hunted down by Mario Prausa.
