Haven't looked at this myself, but this strikes me as an excellent
diagnosis.

And, it's reasonable that more "pressure" is put on _ffestw_ in g77 0.5.25,
due to the rewrite of how some code-generation aspects are handled -- I
believe the rewrite causes, among other things, information on blocks
to be kept around longer than before, to accommodate the new code
generation.  (The new chapter on the front-end design in the docs should
explain things somewhat better.  Of course, I have lots to work to do
improving just that chapter, among many other things....)
