Re: Fix problem causing g77 regressions


    Prior to your changes, n-as-an-array-extent (line 5) would remain
    unchanged when n was assigned to; this protection is arranged by
    wrapping the variable extents of arrays in a SAVE_EXPR, which -
    obviously - lost its protective power due to your changes.

Can you be a bit more details: what was the tree like before and after the
change?  Was anything in sight TREE_READONLY?
