Ok, in db turbo it works too. Ldosbox and mdosbox are on arm8. I can build 32 binaries
EDIT : I found something. With latest Android Studio I experience this and one other problem. With older android studio is everything allright.
I must check it deeper, one time it works and another time no, this is weird
EDIT2:
Seems ldosbox on arm8 cpu suffers of same issue. Please can someone confirm it too? To reproduce it do following : delete CHOICE.DAT, start game and race a bit with car. Quit game by pressing several times the esc key to dosbox console and restart dosbox. CHOICE.DAT should be now recreated. Startup should hang now .
