Research direction
Start with the attached 9525-ms-bug-repros.zip command-line test case and the behavior of the <forward_list>, , and implementations in Debug mode. Reproduce the low-memory scenario and trace the default constructors; done means the reported terminate() behavior is addressed without violating the stated noexcept requirements.
