Use -r rather than -i for the "via stdin" tests.
TShark, at least when running in one-pass mode, now supports reading
from the standard input if the file format is one that *can* be read
purely sequentially; both pcap and pcapng can be read purely
sequentially (unlike, for example, Microsoft Network Monitor format,
where you have to read the frame table, at the end of the file, before
you can read the frames, meaning you have to seek backwards, which you
can't do on a pipe).
Using -r 1) tests the "read from standard input" path, which we should
do in versions that support it, and 2) means we can check whether, for
the crashes we're seeing on 32-bit Windows 8.1, it's a problem with
reading from the standard input in general, or just a problem with
*capturing* from the standard input.
