Double free in `AlignedBox<[T]>::realloc_with_default` when an element's `Drop` panics

Shrinking an AlignedBox takes ownership of the buffer out of self.container with ManuallyDrop::take, destroys the elements past the new length, and only then commits the new Box back into self.container. ManuallyDrop::take moves ownership but not the bits, so until that commit self.container stil...

Double free in `OwnedAlloc::drop_in_place` when the contained value's `Drop` panics

OwnedAlloc::dropinplace destroys the contained value by hand, then commits the ownership transfer with mem::forgetself — which lives inside intoraw and so runs only after the destruction. T::drop is user code and may panic. If it does, the forget is skipped and the still-live OwnedAlloc unwinds,...
