    Bug#48459: valgrind errors with query using 'Range checked · 185e24d5

    for each record'
    
    There was an error in an internal structure in the range
    optimizer (SEL_ARG). Bad design causes parts of a data
    structure not to be initialized when it is in a certain
    state. All client code must check that this state is not
    present before trying to access the structure's data. Fixed
    by
    
    - Checking the state before trying to access data (in
    several places, most of which not covered by test case.)
    
    - Copying the keypart id when cloning SEL_ARGs
