Hello Cygwin community.
I'm observing some unusual behavior with tar v1.28, running as part of
32-bit Cygwin on a Windows 10 machine.
It's probably best if I just walk through a couple of steps to demonstrate.
$ tar cvf dac.tar *
file1.txt
file2.txt
HelloWorld.c
So I can create a .tar file with three text files in it. The first two
are empty, created with the "touch" command.
$ tar tf dac.tar
file1.txt
file2.txt
HelloWorld.c
Displaying the contents of this .tar file works fine.
$ gcc -o HelloWorld HelloWorld.c
$ ls
dac.tar file1.txt file2.txt HelloWorld.c HelloWorld.exe
$ rm dac.tar
$ tar cvf dac.tar *
file1.txt
file2.txt
HelloWorld.c
HelloWorld.exe
So I can apparently create a .tar file with the three text files and the
.exe produced by compiling the C program.
$ tar tf dac.tar
file1.txt
file2.txt
HelloWorld.c
tar: Skipping to next header
tar: A lone zero block at 12
tar: Exiting with failure status due to previous errors
But when I try to view the contents of this .tar file, tar seems to have
trouble with the .exe file.
$ mv HelloWorld.exe dac.exe
$ rm dac.tar
$ tar cvf dac.tar *
dac.exe
file1.txt
file2.txt
HelloWorld.c
$ tar tf dac.tar
dac.exe
tar: Skipping to next header
tar: Exiting with failure status due to previous errors
If I rename HelloWorld.exe to a name that collates before file1.txt,
then "tar tf" stops at the .exe file.
The behavior is the same if I try to extract the archive with "tar
xvf". In that case a dac.exe does get extracted, but trying to run it
gets a segmentation fault (the program just prints "Hello world").
$ tar --version

A similar sequence on a Windows 8.1 machine running tar v1.27.1 does not
produce this problem.
Is there an additional option that needs to be specified for tar v1.28
if an archive includes files like .exe files?
I can try downgrading to v1.27, but I thought I'd see if anyone has any
insights first.
The output of a cygcheck command is attached.
Note that I do subscribe to the mailing list under a different email address. I tried to send this message using that address, but I got back an error 552 (span score exceeded threshold)

Why are you text-mounting it? Is your current working directory
somewhere under that text mount? It may be a bug in tar's handling of
text-mounted files (ideally, tar should be reopening everything binary
in spite of text mounts, but I may have missed a spot).

Could be an accidental regression in my cygwin-specific patches between
the two versions. But I don't normally use or test on text-mounts, so
I'll need confirmation that you are indeed experiencing the problem only
in your text mount, before I spend cycles debugging it.

My apologies if some people see this twice. I didn't see my original reply come through the mailing list.

Why are you text-mounting it? Is your current working directorysomewhere under that text mount? It may be a bug in tar's handling of
text-mounted files (ideally, tar should be reopening everything binary
in spite of text mounts, but I may have missed a spot).
Text mounting is our standard here. I will try to find out why.
I changed the /etc/fstab so it specifies "binary" instead of "text", and with that change, the problem doesn't occur. However, the problem doesn't occur with "text" specified on two other systems that use tar v1.27, one running Windows 8.1 and the other running Windows 7. In fact I had used the "tar" command previously on this Windows 10 system with "text" in place without problems. I've done other Cygwin installs since then, so probably either the "tar" command itself got updated or something it depends on got updated, such that now this issue occurs.

Text mounting is VERY, VERY, VERY bad idea.
Never do that again.

The problem with text mounts is that you can never know, how a given program
would handle it. It may even not in the program's hands, as certain libraries
behind it may have their own second or even third opinion on the subject.
And when you tell the program to read N bytes, you never know, if it will stop
after reading N, or M, or N+M...

For what it's worth, I recently had the similar issues with Cygwin tar
on text-mounted volumes in the last year. We had users moving between
Cygwin tar and Redhat tar and there were issues extracting the tar
files. I instructed them to create a binary mount for tar-related
purposes and that addressed the issue. We need to use text-mounts, in
general, for other reasons. It would be great if tar could be
adjusted to operate properly in these scenarios.

In fact, I missed LOTS of spots. My cygwin-specific patches to 1.27
were accidentally not copied to 1.28. I'm fixing it as part of
packaging 1.29, which should hit mirrors soon.
I'm actually a bit surprised that there were so few reports of this
problem in the meantime (I built 1.28 in May 2015, this report was in
March 2016, and I didn't find much else about it in the meantime).
Maybe that means that text mounts are used much less than they used to
be when I took over building tar in 2005, back when setup.exe used to
have a now-removed option to create text mounts at install time.
