No, it cannot happen. The problem is that _gst_make_oop_weak is used
both in prims.def:
if (!IS_OOP_WEAK (oop1))
_gst_make_oop_weak (oop1);
and when loading images to bring _gst_mem.weak_areas in sync with the flags:
if (flags & F_WEAK)
_gst_make_oop_weak (oop);
so you cannot just return if F_WEAK is already set in the OOP. But
making it an abort would be a good idea indeed.
