I don't implement NT_FILE with no specific reason. I'll accept a patch
for it if you make.

-f option is based on the kernel's coredump_filter, which is utterly
irrelevant to NT_FILE.
I don't see the address translation error. It's necessary to look into
a memory dump for investigation. But you can use -v option to enable
progress information and you may use it to recognize in what phase in
gcore command the address translation error occurs.

There is no public repository of crash-gcore-command. I have a git
repository in the office and I release the latest version of it as
source code now.
Thanks.
