It panics in the same place as in old issue:
src-d/gitbase#544
Now, we have a pool of matchers and it's still happens on 96-core machine.

So far, I think the problem happens when multiple threads reuse the same matcher (I'm not sure if it can happen) and other thread resized the region:
https://github.com/kkos/oniguruma/blob/341002b8a188494871d38fb19ad9d7d44f6aec00/src/regexec.c#L4723

It's not a race.
For sure it happens in the onig_search function (https://github.com/kkos/oniguruma/blob/master/src/regexec.c#L4700)
Even if we have a pool of resources + extra mutex which I added (https://github.com/src-d/gitbase/blob/fix-jenkins-oniguruma/vendor/github.com/src-d/go-oniguruma/regex.go#L204)
it still happens (and not randomly but for every jenkins build):

I'm closing this issue, because it won't be fixed - we switched back to go regexp engine (so far).
