The '<' operator is reserved for future use

This was not supported in PowerShell v1 [and as of v5, it's still not...]

An example workaround is:

Get-Content test.full | .\test_cfdp.exe | tee test.log

powershell redirect io-redirection

Also try:

cmd /c '.\test_cfdp.exe < test.full | tee test.log'

powershell redirect io-redirection

I have switched to linux shell and it works
