Crash still occurs when building the following code:

void bn_sqr_comba8(unsigned long *r, unsigned long *a)
{
        unsigned long t1,t2;
        unsigned long c1,c2,c3;

        asm ("mulq %3" : "=a"(t1),"=d"(t2) : "a"((a)[1]),"m"((a)[0]) : "cc");
        asm ("addq %0,%0; adcq %2,%1" : "+d"(t2),"+r"(c1) : "g"(0) : "cc");
        asm ("addq %0,%0; adcq %2,%1" : "+a"(t1),"+d"(t2) : "g"(0) : "cc");
        asm ("addq %2,%0; adcq %3,%1" : "+r"(c2),"+d"(t2) : "a"(t1),"g"(0) :
"cc");
        asm ("addq %2,%0; adcq %3,%1" : "+r"(c3),"+r"(c1) : "d"(t2),"g"(0) :
"cc");
        asm ("mulq %2" : "=a"(t1),"=d"(t2) : "a"(a[1]) : "cc");
        asm ("addq %2,%0; adcq %3,%1" : "+r"(c3),"+d"(t2) : "a"(t1),"g"(0) :
"cc");
        asm ("addq %2,%0; adcq %3,%1" : "+r"(c1),"+r"(c2) : "d"(t2),"g"(0) :
"cc");
        asm ("mulq %3" : "=a"(t1),"=d"(t2) : "a"((a)[2]),"m"((a)[0]) : "cc");
        asm ("addq %0,%0; adcq %2,%1" : "+d"(t2),"+r"(c2) : "g"(0) : "cc");
        asm ("addq %0,%0; adcq %2,%1" : "+a"(t1),"+d"(t2) : "g"(0) : "cc");
}
