CI is failing. You've modified prelude, which means you'll need to update the minified prelude (manually for now, see discussion in #765). I suspect that's why.

Try to follow the steps outlined in the commit message of 9c69860 and let me know if you run into any issues.

Hmm, so this is not automated yet?

Oops, I did minifying with a wrong text?

I'm not getting the same minified output as you @hajimehoshi. My output is exactly 32740 bytes. Yours is 41045, which is significantly larger than the previous size of 32762.

How did you create this? Did you minify the value of the Prelude constant or something else?

The way I do it is with the help of goexec:

$ goexec -quiet 'io.WriteString(os.Stdout, prelude.Prelude)' | pbcopy

That prints the value of the Prelude constant to stdout, and copies it to my clipboard (on macOS). Then I paste that at https://skalman.github.io/UglifyJS-online/ and get the output.

I used command-line uglifyjs installed by node, and I think that's why the difference caused.

The logic of the change makes sense to me. The values being assigned to s.$length and s.$capacity are unchanged. It's just that high and max are given a logical value earlier and get checked for being out of range.

Just some minor comments/suggestions.

What do you think about moving this test and placing it next to TestSliceOfString, since it's quite similar and related?

There's no need to use numbers so large, the same issue would happen with make([]byte, 4) and a[8:], right? Maybe it's better to use those smaller numbers to make the test focus more on the underlying issue and less resource intensive.

compiler: automate regeneration of prelude (#784)
e1d10e7 
This is a rebase of #765.

Whilst rebasing #669 I fell into a similar trap to #775 (#775 (comment)),
by forgetting to commit the manually minified prelude.

Then going through the manual process of manually minifying the prelude I wasted a whole load of
time installing goexec, missing something the first time etc, issues that this PR addresses by
automating the process, as previously discussed (#765 (comment)).
