It's during compilation cc -c file.c, not a run time sig11 of the program.

It's (sure a bad example of programming practice) the following code 
snippet which emerged after modifying an example (a question) posted
in another maillist.


multiply(char c)
{
   short int r;
   asm volatile ("
        movb $2,%%eax
        imulb %0
        movw %%eax,%1"
        : "=1" (r)
        : "0" (c) : "eax" );
   return r;
}                             

The crucial point is the char c in the parameter list causing
the FreeBSD cc1 to sig11.
