Bug #28362 contains a self contained example. Basically, it needs only
| some_struct = *some_other_struct;

One thing we have is some extra virtual operands from CCP:
before:
bb 2:
mask_5 = old;
v_7 = mask_6;
# SFT.2_33 = V_MAY_DEF SFT.2_32;
*mask_5 = *v_7;
mask_8 = mask_6;
v_10 = v_9;
i_11 = 0;
goto bb 4 (L4);
