Hm. I haven't thought about it enough to give you a fool-proof plan, but one possibility could be to store the MemRegion in the state at the point of the CXXBindTemporaryExpr, rather than just a boolean flag. I don't quite know what the ramifications of that would be, though.

(By the time we get to the destructor, the value of the CXXBindTemporaryExpr is almost certainly no longer in the Environment.)
