Well, tests against 2.6.0 do not fail on my development machine 🤷‍♂️

Thank you @tagliala

[tagliala]

@bblimke you're welcome, thanks for the release

Do you know what could be the origin of the failure on Travis CI?

[bblimke]

@tagliala I have no idea. On my machine all tests pass on 2.6.0. Perhaps some differences in Ruby build.

[ahorek]

It fails for some time only on ruby 2.6 and master not always but pretty often. I'll try to simulate it locally.

[ahorek]

I was also unable to simulate it locally, all tests pass... weird
