fatal - machine stack overflow in critical region

[jfabre]

Hello, I'm having a weird issue that occurs on very specific circumstances on my rails app.

I got a fatal exception getting thrown that seems to come from warden.
Any help would be appreciated, I have no clue what to look for here.

ruby 2.7.1
rails 6.0.3.5
warden 1.2.9

I'm on Ubuntu 20.04.2 LTS (GNU/Linux 5.8.0-44-generic x86_64) if that is useful.
I've added the whole error as an attachment.

Thank you and have a good day!

A quick look at the error and looking at the Ruby tracker turned up 11903. It looks to be something with Ruby itself
