Mmm... true. My patch "just works" but it must be overwriting some data
on the stack when I use a stack gap size > STACKGAPLEN.

I'm running out of idea about how to handle this problem. Maybe store
temporary data somewhere else? Or just make it bigger and hope we never
hit a case where it does not fit?
