Works just fine for me:

$ tar ft Downloads/nam.dist.tar

You may have some interfering like an AV.
  The strace shows tar fails in sysfer.dll, which is part of Symantec Endpoint
Protection CMC Firewall Application and Device Control, badly written from the
number of complaints about it, and as usual with these control and monitoring
products, they greatly slow down systems and interfere with work.
Deinstall SEP or bypass your cygwin directories.

Take care. Thanks, Brian Inglis, Calgary, Alberta, Canada
