It's not so much the re-ordering but the pot

Does removing it actually make a difference? I can't spot anything
which could reasonably be reordered around the asm() blocks.

The memory clobber is rather harsh here. However, fic.exn_raised may be

of "fic" may be changed (preventing it from moving around accesses to
the exn_raised field).
