--- Comment #1 from Daniel Grunwald <daniel.grunwald at gmail dot com> ---
Confirmed with libstdc++ 16.1.0: this issue is segfaulting our program that is
directly using repeated calls to `sputc()` without checking the return code.
I do not see any requirement in the standard that the stream must be in a valid
state for the `sputc()` call, so I think this is a library bug.
