I'm not able to reproduce this, either when Falcon mode is set in Hatari 
config, or from command line.  Switching to ST mode at run time works 
fine for me in both cases. Address Sanitizer does not report anything 
either.

Can you still reproduce it with latest Hatari Git version?   If yes, 
could you send your Hatari config (hatari.cfg), and built config 
(CMakeCache.txt) files to me?
