Crash Swift/ContiguousArrayBuffer.swift:691: Fatal error: Index out of range whenever loading a simple text file

[aleroot]

Simply try to load the String of the simple text file attached with:

        let parseOptions: Markdown.ParseOptions = [.parseBlockDirectives, .parseSymbolLinks]
        let document = Document(parsing: markdown, options: parseOptions)

The library crashes with: Swift/ContiguousArrayBuffer.swift:691: Fatal error: Index out of range

If I change to :

        let parseOptions: Markdown.ParseOptions = [.parseBlockDirectives, .parseSymbolLinks]
        let text = markdown.replacingOccurrences(of: "\r\n", with: "\n")
        let document = Document(parsing: text, options: parseOptions)
        var resumeGenerator = ResumeHTMLGenerator()

I get Swift/ContiguousArrayBuffer.swift:691: Fatal error: Index out of range as well
