When you say "produce a core dumps" what exactly you see. How do you know it produces the kernel dump?
I usually build the AUR package from within X. But sometimes I do it on another TTY. On these cases where I do it from TTY I was able to see partly a core dump (messages about kernel panic and then some more output). The problem was that it was part of it and I could not scroll to see the whole message.
After the crash happens kernel cannot write anything to disk nor send via network. Dealing with disk/network/... requires valid kernel data structures and you don't have them anymore.
Once kernel crashed it has only one option - reboot.
Check kdump https://wiki.archlinux.org/index.php/Kdump - it is probably what you are looking for.
But that invoves a kernel compilation (right?) and I seem to end up in the same problem as before - kernel crashing when compiling big projects. Is there a kernel with Kdump enabled already? --
