I suppose the counter is outdated, similarly to D104925#2850420?


Shouldn't this be all you need to retrieve the fact that the streams position is indeterminate?

This will be rebased on D104925 when that is finished.


The "problem" can be that the error state can contain a combination of errors, this means FEOF and FERROR together. In this case the "indeterminate" is just not applicable to the FEOF state.
