Yes, the gcore.tar.bz2 file would be best. That way, you can make
updates whenever you want, without having any reliance upon any
crash utility release.
OK. I'll post that way, and I'll also give description explaining what
is added in the release.
Also, if you have a public location where perhaps a git tree exists,
we can put a link to it in the comments section of the web page.
Or if you want add more to the description in the "comments" section,
(perhaps the kernel versions it has been tested with?), the let me
know.
In any case, the new files are now available from:

Thanks. It's helpful. I'll let you know after I consider what's needed
to be described. I've not yet have git tree in public but it'll help
if exists. I'll consider that from now on.
Also, I have a question about the fact that gcore hanged during the
process of gathering note information.
I attempted reproducing the bug on 2.6.35.10-74.fc14.x86_64 with
crash-5.0.6-2.fc14.x86_64 and crash-5.1.1, but it have not been
reproduced yet: gcore worked well for both crash versions.
I then retried using 2.6.34-2.fc14.x86_64 but failed to boot on the
same environment as in 2.6.35.10-74.fc14.x86_64.
So, questions I have are: In what kind of environments did you face
the hang? I want to and need to set up the same environment as
yours. In Fedora Alpha, its kernel version was already 2.6.35
according to the release notes:
http://fedoraproject.org/wiki/Fedora_14_Alpha_release_notes#Linux_Kernel_...
Also, it is helpful if you show me a backtrace during gcore hanging.
Thanks.
