indeed, the testcase you submitted as part of libstdc++/6750 is
sensitive to this recent change, since, after terminating a getline with
a single delim char ('\n') the buffer turns out to be empty and triggers
the new code checked in by Benjamin.
If I understand well libstdc++/6518 commit, the new code is tought to
deal more gracefully with the undefined behaviour (avoiding a core
dump), but still sets the badbit. A few other implementations, however,
don't set it.
Benjamin, what about not setting the badbit in v3 too?
