Panic original_doc.len_chars() == self.len

[wucke13]

I got the following during editing Rust code, I only recall having pressed u multiple times to revert changes.

thread 'main' panicked at 'assertion failed: original_doc.len_chars() == self.len', helix-core/src/transaction.rs:275:9

I'm using helix 0.5.0

I think we can't really do much here if there is no stack trace or step to reproduce, should it be closed?

Needs more info

I haven't encountered this since, so unfortunately I can't provide more info other than that the given source code line assumes an invariant which is untrue in some circumstances

I just encountered this bug. Also without backtrace enabled and unfortunately I haven't been able to reproduce it.

$ hx --version
helix 22.08.1 (66276ce6)

thread 'main' panicked at 'assertion failed: original_doc.len_chars() == self.len', helix-core/src/transaction.rs:265:9

I had just performed a clipboard-paste-after followed by u.

Edit: Unlikely to be useful, but here's some more system info.

$ uname -rvmos

Also just encountered this and don't have a reproduction after a middle click paste and an undo:
