The fold command crashes! :-(
It works in a debian system (2.6.16 kernel), but I can't say for sure if it's an upstream problem or not.

Here are a log:

A friend has triend and reproduced the bug on a Gentoo system; so I guess it's upstream.

How can I build this with abs and makepkg such that debugging information is added?

I have installed "gdb" and "ddd" but the fold binary lacks debugging symbols (apparently).
Comment by Jens Adam (byte) - Friday, 08 September 2006, 08:01 GMT
Add "options=(NOSTRIP)" to the PKGBUILD.

Still I get the '(no debugging symbols found)' :-(

I suppose this is fixed in coreutils 6.4 ?

Comment by Andreas Radke (AndyRTR) - Wednesday, 27 December 2006, 17:08 GMT
same here (x86_64). but i don't know why you give the command 2 files. as long as you give only one file it works well. i've never seen this command in that way. maybe you want it like that: fold /etc/host.conf > /etc/host.conf ?
Comment by Henrik Holst (holst) - Friday, 29 December 2006, 13:22 GMT
It does not make sence to try another test. This is how you recreate the bug (with a non-empty host.conf file):
[code]
$ fold /etc/host.conf /etc/host.conf > /dev/null
[/code]
The man page says you can do like this; so fold should not crash.
Comment by Tobias Powalowski (tpowa) - Friday, 29 December 2006, 13:24 GMT
this is a arch 64 bug and not a i686 one assigning to andy again
Comment by Andreas Radke (AndyRTR) - Friday, 29 December 2006, 14:17 GMT
i don't know exactly the usage for this command. but from what i read about it (http://www.computerhope.com/unix/ufold.htm) i guess you don't use the right syntax. or can you explain what the command should do?
Comment by Henrik Holst (holst) - Friday, 29 December 2006, 14:52 GMT
Why don't you use the GNU man page?

The man page of fold command in coreutils:

http://www.mypastebin.com/?code=143889507

It's rather clear that it should support many files.
Comment by Andreas Radke (AndyRTR) - Friday, 16 February 2007, 06:47 GMT
i can still reproduce it. another x86_64 developer doesn't have that bug. can you please try to contact the coreutils developers?
