You're welcome. I hope this is helpful in your efforts.

Larry,
Can I just jump in here and say thanks for doing this quick intro to debugging?
The closest I've come to gcc and gdb was using DJGPP about eight years ago and it's hard to know where to start when things go wrong. This should get me started next time something does...

We'll make a developer out of you yet! :-)
You'll need to run setup and install the 'gcc' package (not gcc2) and the 'gdb' package. That should install everything you need as a build environment. You'll also want the source for tar. Get that from setup too. Once done installing, do the following:
1. cd /usr/src/tar-1.13.25-1/ 2. ./configure CFLAGS=-g 3. make
Now you can try this version to see if your problem reproduces. The new 'tar' is in ./src. If you can reproduce the problem there, try it in gdb. To do so, type 'gdb src/tar.exe'. At the gdb prompt, type 'r <command line parameters that you give to tar to reproduce the problem>'. This will start it running. When you think it's to the point where it's hanging, type ctrl-c to stop it and then 'bt'. This will tell you where you are. You can step through the code with 'n'. Presumably, you'll see you're cycling through the same statements at some point.
This may not point out the source of the problem to you, although you'll have more information to report to the list about the case you're running into. The steps you took, things you saw, and the result of 'bt' (initially at least) may help someone on this list spot your problem.
Good luck and enjoy! ;-)

Which I've never done; I'm not a cygwin developer, just a user. Do you remember where cygwin documents how to set up a build environment and get a build going?

Any suggestions how I can proceed to debug why tar acts the way it does for me and not for you?
I think you're down to building and debugging the code.
