Hola 
Tengo un problema. 
Esta rutina no da problemas al compilar pero si la compilo en Red Hat 6.2 funciona bien.
Pero si la compilo en Red Hat 7.1 al ejecutarlo me da violaci�n de segmento.
�Existe alguna forma de compilar en Red Hat 7.0, y que no de este problema?
Esta rutina es critica y se debe ejecutar como root.

Tambi�n, otra pregunta,� Ha desaparecido randomize en el nuevo compilador?


void outportb(unsigned short port, unsigned char value)
{
__asm__("
	  pushw %%dx\n
	  pushw %%ax\n
	  movw %1,%%dx\n
	  movb %0,%%al\n
	  out %%al,%%dx\n
	  popw %%ax\n
	  popw %%dx"
	  :
	  : "g" (value), "g" (port)
	  : "ax","dx"
	);
} 

Gracias
