 Is this still happening? When I use "./mame ti99_4a -listxml", I am not getting any runtime error but a XML output. (Version 0.260)

 These appear to be errors detected by UBSAN, and will probably not occur in other builds.

 I see. It's complaining about each occurrence of the static cast like

void contained_device::device_config_complete()
{
   ptr_containing_device = static_cast<containing_device*>(owner());
}

Is that bad code? I need a pointer to the containing object to call methods on it, so how should it be done better?

 Your device needs to survive -validate, -listxml, -listroms, etc. where it's instantiated in isolation. You could use a dynamic_cast instead and be prepared for nullptr in those cases.

 OK, it does survive the -validate etc., but I'll replace the static_casts by dynamic_casts. Thanks for the tip.

 Please test the latest update, I replaced the casts now. Looks good to me.
