emacs 30.1 seg faults on Fedora 41

[logexp1]

In org-mode, when I run org-babel-execute-src-block, emacs crashes. This is the message from dmesg | grep emacs

[ 3552.608878] emacs[78444]: segfault at 738ed0 ip 00007fe8fc9b4948 sp 00007fff2f8076c0 error 7 in emacs-zmq.so[a948,7fe8fc9ab000+b000] likely on CPU 5 (core 8, socket 0)

which seemed to be exactly same errors in https://github.com/emacs-jupyter/jupyter/issues/212#issuecomment-1312309618 (I built emacs from source of version 30.1, though)

I tried to troubleshoot emacs-zmq (my zeromq version is 4.3.5) based on this https://github.com/nnicandro/emacs-zmq/issues/14, and I am getting similar debug messages under gdb (my gcc version is gcc (GCC) 14.2.1 20250110 (Red Hat 14.2.1-7))

from https://github.com/nnicandro/emacs-zmq/issues/14#issuecomment-1493311040, it is said build without xwidget support had a success, but that's not my case.

can anyone help me?

Thanks.
