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?

@SirVer Of course, though it's so simple I assumed it wasn't relevant:

snippet assert_eq "An assertion" b
assert_eq!(
    ${1:A},
    ${0:B},
);
endsnippet

[SirVer]

Indeed, that snippet should not trigger such behaviour easily. So much more likely that there is interplay between UltiSnips and a different plugin.

Please provide a fully reproducible example, ideally using the approach explained in https://github.com/SirVer/ultisnips/blob/master/CONTRIBUTING.md#reproducing-bugs or if not possible with a minimal vimrc and snippets files and an exact sequence of key strokes that trigger the bug.

@SirVer I wish I could, but as I said in the original post, I'm unable to replicate it consistently, it seems to happen at random. It seems to be related to the interweaving of UltiSnips snippets and LSP snippets. It hasn't happened for a few days now (since I was working on a Rust project), so it might even be specific to the rust-analyzer LSP.

From now on, I'll make note of what I'm doing when this crash happens, and hopefully a pattern will emerge.
