Flåklypa Grand Prix is an old (2001), Norwegian PC-game with CD-Cops protection (http://www.gamecopyworld.eu/games/pc_flaklypa_gp.shtml).
It would be nice to get this game to run without cracking it.

--- Comment #1 from Michael Müller michael@fds-team.de --- Your problem is not a Wine Staging regression and therefore belongs to the Wine product.
Actually, it is not a real Wine bug either, but a configuration problem. The memory allocation is implemented in Wine, but your kernel denies allocating memory in this area. For security reasons, recent kernels define a minimum memory address for allocations. The limit can be changed through /proc/sys/vm/mmap_min_addr. When setting the value to zero, the error message should go away. When using SELinux, you also need to allow low area memory allocations for Wine, otherwise you will run into the same problem again.

Thanks :)
Now I've got past this hurdle, but it still fails. Now I get the following error message:

--- Comment #3 from Michael Müller michael@fds-team.de --- The next problem is easily visible in the log. The application tries to setup a protected mode exception handler (int 0x31 - AX 0x203) for debug exceptions (0x1), but this is not yet implemented in Wine. Afterwards the application triggers a single step exception that should be forwarded to the registered exception handler. Wine ignores this and can't handle the exception itself, eventually terminating the application.
I don't think it would be terrible difficult to implement this in Wine, but I fear the chances are low that someone capable of implementing this owns the game. Writing tests for DOS functions is also quite difficult.

--- Comment #4 from Håkon haakobja@gmail.com --- I'm willing to provide my backup cd if that would help to implement a fix for this. I think this would make other games with CD-COPS protection work.
