Yes, but i need to test it with TOS 4.04, because with EmuTOS, everything works ok. That means i have to install hd-driver first. Maybe someone has already a working image and can do a quick check?

 

What i noticed: smurf uses Pexec(3, filename, NULL, NULL) to load the modules. That is, it passes NULL as cmdline. That parameter is not checked by TOS or EmuTOS, and has the effect that the first few bytes from address 0 are copied to the commandline. This alone does not crash, since that is executed inside TOS, in supervisor-mode, but maybe TOS 4.x behaves differently there? Or maybe Hatari does not expect that and generates a bus-error by itself?
