I did so. I rebuilt separately Emacs from scratch from today's
Git repo with no modification on the source using these configure
options
configure --verbose --with-x-toolkit=gtk3
(I detached "CFLAGS=-O0"), run it from gdb, and I got the
backtrace that is in the bottom of the attached GDB log. It
might be too short to analyze, though.

There are 121 threads (IIUC). I don't konw what is the Lisp
thread, sorry.

No, I don't specify -g3 expressly/intendedly. But it came not
to issue an error today for an unknown reason.
(I don't know why but today's Emacs lived for over an hour, so
I was excited over a false hope. The main Emacs that I rebuilt
from Git master today is working fine with reverting the three
changes in question.)
Here is the GDB log. Thanks.
