Issue occurs for me in both 9.2-1 and 9.2-2 but not 9.1-3

Is the result the same if you add the option --reflink=none ? This is testing for [1].

Looks like that's the issue I'm encountering! --reflink=never copies successfully.
Thanks for the quick response

There is this commit https://git.savannah.gnu.org/cgit/coreutils.git/commit/?id=093a8b4bfaba60005f14493ce7ef11ed665a0176 as fix.
So i built https://git.savannah.gnu.org/cgit/coreutils.git/snapshot/coreutils-master.tar.gz and there is not any issue....

AFAIK this only happens in restricted environments. I just hit this bug in an LXC container. Seems to be working find outside of LXC though.

Yeah, I think I'm suffering from this bug compiling AOSP in a podman container.
It happens randomly, but if it happens it will stop the build always at the end of the aosp compilation with a `cannot allocate memory` error.
Probably because of the not working cp and the try to do something with the copied file and the end of the build process.

(Definitely not a ram problem, because I tried with 1 thread and 24GB ram and according to my stats I had many gb's of free ram when it happens)

Upstream patch included in coreutils 9.2-3.
