--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
The EVRP dump with -details isn't very useful, we just see the
folding/substitution phase:

Folding statement: t_5 = __complex__ (3, 0) / c_4(D);
Not folded
Folding statement: v_7 = g;
Not folded
Folding statement: _1 = REALPART_EXPR <t_5>;
Queued stmt for removal.  Folds to: 3

and that looks obviously wrong.
