Details:

cat /etc/centos-release
CentOS Linux release 8.1.1911 (Core)

octave --version
GNU Octave, version 5.2.0

Steps to reproduce:

Install debug symbols
sudo debuginfo-install -y octave

Start octave a few times until it crashes
octave --gui

Copy and decompress coredump from /var/lib/systemd/coredump/core.octave-gui*

gdb /usr/libexec/octave/5.2.0/exec/x86_64-redhat-linux-gnu/octave-gui

core core.octave-gui.*
bt

According to the backtrace this looks like a Qt realted heap corruption:
