## Check that we emit an appropriate warning when the dynamic string table ends past the end of the file.

## right before the EOF. No warning should be emitted.

## as normal. Since the file ends with a zero byte, strings are dumped, but if it didn't,
## we'd get <?> printed instead. The important bit is that we don't get the past the end warning.
