Segmentation fault 11 cURL
There's currently an issue with curl-openssl on mac that affects some people. I have it on one machine but not on another. The curl issue is here: https://github.com/Homebrew/homebrew-core/issues/40812
I've previously tried downgrading curl, re-installing from source etc (this was better but still has some issues)
A curl release should be due today (17th July 2019) to fix the issue
