odd. I can't reproduce the problem. The error is coming from a failed attempt to "seek". Are you sure those are the reproduction steps?

Yes. I use Windows 98SE, if that matters.

hmm. I'll try to find a Win98 box. I was also using dmd.123 but I'm not aware of any bug fixes that should have changed the stream behavior between dmd.122 and dmd.123. Maybe the directory and/or file read/write privledges are different from my first test. It would be useful to know if someone else reading the newsgroup can reproduce it, too.

The solution is to change the following line of std.stream.d:
long diff = bufferCurPos-bufferSourcePos;
to:
long diff = cast(long) bufferCurPos - bufferSourcePos;

whew! thanks for trying that out.
