[Bug inline-asm/32971] Inline asm with offset addressing fails to compile in 4.0+ without -O

Using a memory operand to pass the offset value is not ideal in the first
place, but I'm not sure how else I can do it.  It looks like the "i" contraint
(immediate value) is what I want, but the following code:

  asm ("lea %1(%2), %0"
       : "=r" (i)
       : "i" (offsetof(struct coord, y)),
         "r" (c)
       : "memory");

...generates the following assembly, which gas fails to assemble due to syntax
errors:
        lea $4(%eax), %eax
