Judging frome the fact that the exception object does not contain a
message, it must be coming from one of several of the following checks:
if (ferror(fps))
StdioException();
For example:
https://github.com/D-Programming-Language/phobos/blob/master/std/stdio.d#L4180
And the only meaning is that the input stream is in error state. :-/
