TypeError: Cannot read property 'text' of undefined

See original GitHub issue

not entirely sure if this is an issue with istanbul directly or karma-coverage, but i think it’s an istanbul thing so i created this issue with them but you may want to look into it too:

the problem is:

text = structuredText[startLine].text;

i guess it assumes structuredText[startLine] is always going to be a thing, and apparently at least once it is not a thing? I don’t know how you can reproduce it; just let me know what you need that i can provide and i’ll provide it.

I’m having a similar problem with flow and closure:

this will throw an error:

const test = (arg : string) : Function => (arg2 : string) => false;

this works fine

const test = (arg : string) : Function => {
    return (arg2 : string) => {
        return false;
    };
};

Should I open a new issue?

Not a npm package, juste a reporter config.
