RecursionError: maximum recursion depth exceeded in comparison

[Hubro]

Sorry in advance, but I am unable to reproduce this issue, it seems to happen at random maybe a couple of times per day. I have tried to find a way to reproduce it the last couple of weeks, but I can't. It's annoying me so much I need to post it, in case you have an easy solution.

Sometimes my editor freezes for a long time before I get this error (like minutes), other times I get it instantly after filling out a snippet.

The last couple of times the error happened, it was while filling in a Rust LSP-provided snippet inside of a custom Ultisnips snippet, i.e.:

assert_eq!(
    unique_paths(3, 7),
    28,
);

assert_eq! above is a custom Ultisnips snippet, where I expanded the unique_paths snippet from the LSP in the first position. I got the error when pressing <Esc> to leave the snippet context.

The error is:

An error occured. This is either a bug in UltiSnips or a bug in a
snippet definition. If you think this is a bug, please report it to

Has anybody else had this same issue? Is there something obvious causing it?
