Infinite loop on poetry lock with specific dependency update

Description

When updating torch from 2.9.0 to 2.12.1 on a project poetry lock fell into an infinite loop - could see this by running poetry lock -vv. RAM usage from poetry lock increased and increased over 10-20 minutes until it was using 20GB+ at which point everything crashed.

This wasn't happening when torch was the only dependency. So slowly narrowed down which of my other project dependencies were needed for this bug to show up - narrowed it down to 'flake8-functions-names==0.4.0' of all things.

Note: this only happens if using different source for torch for different architectures - as I want the pypi torch for aarch64 and torch==2.12.1+cpu for x86_64 which comes directly from 'https://download.pytorch.org/whl/cpu' rather than pypi.

Workarounds

poetry lock --regenerate works fine. Which I had realised that sooner.
