--- Comment #4 from Stefan M Freudenberger ---
I guess there wouldn't be an issue if it were a reference type. However, there
is an issue with the incorrect alignment for the object type.

This is the revised patch:
- add_expr = fold_build2 (POINTER_PLUS_EXPR, TREE_TYPE (c->base_expr),

My original example involved a MEM with a constant offset, and yielded an ICE:
