The SSA_NAME does not have a definition any more but not released:

When openmp outlines the basic-block, it must not have released them:
#pragma omp parallel [child fn:
_ZN12_GLOBAL__N_121morphologicalFilter1DIiLi0ELi4EEEvv._omp_fn.0 (???)]
<bb 3> :
vals = .DEFERRED_INIT (96, 1, 0);
D.2608 = &vals + 0;
_1 = D.2608 + 96;
goto <bb 5>; [INV]
<bb 4> :
D.2608 = D.2608 + 24;
<bb 5> :
if (D.2608 != _1)
goto <bb 4>; [INV]
else
goto <bb 6>; [INV]
<bb 6> :
vals = {CLOBBER};
#pragma omp return
I don't see anything exactly related to ftrivial-auto-var-init really except it
adding the loop around vals.
