Hmm. I'm running Xcode 12.0.1 on 10.15.6 and don't see it. Are you sure you have the '&' in front of locs_buf? I.e.,

    The proposed (updated) change does _NOT_ compile on my machine (MacOS 10.15.6, Xcode 12.0):

    sharedRuntime.cpp:2860:46: error: cannot cast from type 'struct (anonymous struct at sharedRuntime.cpp:2859:7)' to
    pointer type 'relocInfo *'

    You will have to use a union (option (2) as proposed by Kim Barrett far above. I proved that variant compiles on my
