Crash When Linting File

[72A12F4E]

When I run SwiftLint against my project, I get the following error.

This error only appears to happen after I build my project for a 2nd time. If I clean the entire project then build, this error does not occur.

This happens immediately when it starts linting a particular file in my project. I am unable to share the file, but I can give some metadata about the file

[me@mac]~ $ wc badFile.swift
     201     478    6539

I am using SwiftLint version 0.14.0

This seems to be a duplicate of #921.

Can you try disabling trailing_comma to see if it stops crashing?

Disabling the trailing_comma rule seems to fix the crash. Thanks!

I'll close this so we can focus the discussion on #921 then. If you could try to reduce the file so a sample example, that'd be awesome.
