If I put your filter into a file, and do

I get the same program.

...although I put the filter into a file on UNIX, so there were only LFs
at the ends of lines, not CR/LFs.

If I create the file with Notepad (good old Microsoft - they let me do

        notepad e:\filterfile.txt

from the command line!), and then try

        .\windump -r {capture file} -dF e:\filterfile.txt

I get

        .\windump: short read e:\filterpoop.txt (156 != 162)

so perhaps tcpdump needs to read the file with O_BINARY set on Windows.
