Stack Level Too deep error when using alpine ruby image

[jottr]

We get a stack level too deep error message, when running our rspec tests inside a container based on the alpine ruby image (ruby:2.5.0-alpine).

This does not happen when using an ubuntu image as base.
It seems that this issue has already been reported on the rspec bugtracker, and on the ruby bug tracker.
This comment provides a testcase for what happens when ruby tries to calculate the stacksize inside an alpine container.

I created this issue, so we can track if this issue has been resolved here, or upstream by ruby devs or musl-libc devs
