OK, to solve that problem it looks as though the best
approach is to make sure the value of the field is
saved when I'm saving the stack and then inject code
which pushes the (new) address of the field when I'm
restoring the stack, which is a faff, but not

I think I've found the cause of my current problems
though with peverify 2 (which seems much better than
1.1 BTW). It looks as though the normal code pushes an
LLVector on to the stack while the restore code
unboxes a boxed LLVector which leaves a Managed
Pointer to an LLVector on the stack. Is there an easy
way to go from the pointer to a value?

Thanks for all your help,
