commit e5e7b57c46d6290a92e7b9d3c4048bdf90d6a2b2

    Fix style tests.

I'm building the Hugo docs site from this PR:

gohugoio/hugo#3891

But the stack trace points to this:

ruleIndex, rule, groups := matchRules(l.Text[l.Pos:], l.Rules[l.State])

Any idea what language was being formatted when it failed? I suspect this is due to the Combined() mutator, which is the only location l.Rules is modified. Though I would have expected to see it in one of the stacks.

Most likely html; maybe bash.

(Whoops, didn't mean to close it.)

Can you test that commit? I moved the Combined() mutation to a pre-processing phase, which is locked behind a mutex.

Your commit looks good, I cannot reproduce it.

These bug reports are entirely out of self-interest (I would much rather fixing them now than having to get mysterious bug reports in the wild), so thanks for fixing them.
