constant dato=allocate(8) atom key, t, arg

arg=allocate(8)

dummy = SDL_Init(SDL_INIT_TIMER)

key=SDL_GetKeyState(NULL)

function Thread(atom dato) while peek(dato)=0 do SDL_PumpEvents() end while return 0 end function

t = call_back({'+',routine_id("Thread")})

constant main_bucle=get_asm( "pushad "& "l1: "& "mov al,[key+27] "& "or al,al "& "jz l1 "& "mov [dato],al "& "popad "& "ret") resolve_param("dato",dato) resolve_param("key",key)

poke(dato,0)

dummy=SDL_CreateThread(t,arg) call(main_bucle)

SDL_Quit()

The only (semi-)easy method that I'm aware of, which is highly platform-specific, would be to rebuild eu.a as a shared library and have SDL_CreateThread() call a C or machine code function that reloaded eu.so via dlmopen() specifying to load (or reload) the library in its own namespace.

It might work by chance for a very small program, but make it larger - or simply have both threads run for a long period of time - and you'll get the same sort of crash.
