commit a7e75ff7966d7d3d83d41a47c5b9fa5e3daa2465
Author: Roger Dingledine <arma@xxxxxxxxxxxxxx>

    don't free the values in options->MyFamily when we make a descriptor
    
    If we free them here, we will still attempt to access the freed memory
    later on, and also we will double-free when we are freeing the config.
    
    Fixes part of bug 22368.
