--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed. The IL we warn about is
B::B() (struct B * const this)
{
struct
{
._0 e;
int i;
int j;
} D.4784;
<bb 2> [100.00%]:
D.4784 ={v} {CLOBBER};
MEM[(struct &)this_2(D)] = D.4784;
return this_2(D);
and we warn about the MEM[(struct &)this_2(D)] = D.4784; assignment.
The warning is clearly correct as the A members are not initialized.
Did you reduce a testcase too far?
