Return a pointer to the string literal "bad_weak_ptr", with a storage duration of the lifetime of the program. Note that the caller should _not_ attempt to free this memory. Note that the `bsls_exceptionutil` macro `BSLS_NOTHROW_SPEC` is deliberately not used here, as a number of standard libraries declare `what` in the base `exception` class explicitly with the no‐throw specification, even in a build that may not recognize exceptions.
