Curl Easy segmentation fault with requests to external site about node-libcurl

[jeremydenoun]

If this can help people about this issue, this is related to openssl version in alpine (3.19 and lower) after analysis deeper the issue (I have the same in my usecase) with segfault handler trapping, I can see this kind of trace

I switch to debian 12 image (standard or slim) for testing and this work correctly (without segfault)

Same here. Using this package (whether through curly or new Curl()) works on a local URL, but causes a Segmentation fault on an external URL. I'm running Node using docker-compose.

Hey, thanks for the detailed reproduction steps! Right now I am not finding time to look into this, I know it is usually not feasible, but if possible try using a non-alpine image to see if the issue persists.
