I'm writing a complex patch that uses a lot of line~ and that, once every 5-6 times, crashes reporting the log that I paste below.

Does anybody know exactly when this "line_perform" may crashes?

Let's have a look at the patch. What are you doing to cause this?

it is a very complex patch, and I have no idea which of them causes the issue.

That's why I would like to get a brief explanation of this kind of crash, if it's possible.

Too many messages at the same time maybe?
