Huge memory usage in Pop OS 22.04 (Ubuntu)

Dear all,

After a month of not using gmsh, I realized that .geo scripts that I used to run in my laptop not longer works and observed a huge memory usage. I have replicated the same behavior using gmsh 4.8.4 installed from ubuntu PPA, binaries of gmsh 4.11.0 and 4.11.1, and compiled versions of 4.8.4 and 4.11.1. However, using gmsh in a Docker container in my laptop and desktop computer with the same SO work as expected.

Below is the ouptut of running the t1.geo example (which was stopped after 1 minute of running) and a screenshot of resources consumption obtained with htop just before stopping the process.

Any ideas about what could be happening or how to further track the issue?

Thanks in advance!
