When inserting nodes into a forward list, each new node is allocated but not constructed. The constructor was being called explicitly on the node `value_` but the `next_` pointer remained uninitialized rather than being set to null. This bug is only triggered in the cleanup code if an exception is thrown -- upon successful creation of new nodes, the last incorrect "next" value is overwritten to a correct pointer. This issue was found due to new tests added in https://reviews.llvm.org/D149830. Differential Revision: https://reviews.llvm.org/D152327
