This time I build it with Debian package way, but I should build with
upstream tar first. I would like to get your help here how to debug
the issue effectively?

TIA,

BR,
Bo

My suggestion is to run the failing command under GDB, and when Emacs
crashes, produce a backtrace and post it.

To see the failing command, say "make V=1".

Also, please post the configure command you used to configure the
build, and also please tell which version of Emacs you tried to build.

The issue maybe due to libgccjit-13-dev:
https://bugs.launchpad.net/ubuntu/+source/gcc-12/+bug/2011487

So if not to pass with-native-compilation to build on Debian riscv64:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1050653

I will always put my eyes on the issue.

BR,
