Since subclasses could override the seek method without setting the file descriptor.

Great! Funny how easy it is to miss stuff like this. |

Indeed, I wonder if this would ever be discovered if it didn't cause a runtime error. For further readers; note that the severity of this issue is low, as the invalid parameter error only seems to happen on Windows when linking against UCRT, which our Windows 32- and 64-bit binaries does not link against. |
