The following code breaks when compiled with -O3 or -O2, because the label 
seems to be misplaced.  This problem seems to be restricted to situations where 
I pass the address of a label into an assembly routine to be used.  When 
compiled without optimizations or with -O1, it works properly.  I´m compiling 
in FreeBSD 5.3-RELEASE gcc version 3.4.3, and I have confirmed that it occurs 
also on Knoppix 3.6 with compiler version 3.3.4.  No flags other than 
aforementioned optimization flags were used in any case.  I hope this is enough 
info. 
 
main() 
{ 
        puts("This line should print.\n"); 
 
        asm("jmpl *%0\n":: "q" (&&foo)); 
        puts("This line should not print"); 
foo: 
        puts("And this line should print.\n"); 
}
