--- Comment #8 from Richard Biener <rguenth at gcc dot gnu.org> ---
So it's "easy" to explain. The initialization gets optimized away because
appearantly points-to analysis concludes that the allocated storage does
not escape:
a_3 = &HEAP(10)
CALLUSED(12) = &STRING
_4 = a_3
D.3422 = a_3
callarg(19) = &D.3422
callarg(19) = *callarg(19) + UNKNOWN
CALLUSED(17) = callarg(19)
derefaddrtmp(20) = &NONLOCAL
*a_3 = derefaddrtmp(20)
-> ESCAPED, points-to non-local, points-to vars: { }
but this should have included HEAP(10).
Let me investigate. It might be still a FE issue.
