Segmentation fault 11 cURL

cURL "Segmentation fault: 11"

At some point, I wasn't able to use any php or c (these are the ones i checked) programs that use cURL without the segfault. Nothing has changed besides an xcode update with additional packages. My colleagues do not have this problem though. I can use cURL manually which works, for example:
"*- ~$ curl -I https://www.google.com/"
Initially i thought it was a problem caused by php but it works perfectly fine as long as no cURL is used.

Things I tried:

System:

Coredump:

lldb:

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
