[PATCH] D12616: Failing test highlighting no poisoning if dtor undeclared.

[Naomi Musgrave via cfe-commits]

If class or struct has not declared a destructor,
no destsructor is emitted, and members are not poisoned
after destruction. This case highlights bug in current
implementation of use-after-dtor poisoning.
