rbenv crashing when installing ruby binaries

Question

I updated this Lenovo laptop to Ubuntu 22.04 LTS, installed Ruby (3.1.2), rbenv (1.1.2), then Rails (7.0.3) without issue. However, rbenv consistently crashes when I try to install new ruby executables. Thus far I've tried 2.7.2 (compatible with an old Jekyll blog) and 3.0.2. GCC 11.2.0 is being used for compilation. I've reviewed the ruby-build log but don't yet understand how to proceed.

2.7.2 compilation output shown below. Ideas?

Install the following dependencies (rbenv/ruby-build wiki), then try building/installing ruby.

$ apt-get install autoconf bison build-essential libssl-dev libyaml-dev libreadline6-dev zlib1g-dev libncurses5-dev libffi-dev libgdbm6 libgdbm-dev libdb-dev
