Getting segmentation fault when running the application. Only on HTTP client request sending to external API. The app start fine and I can navigate fine, but whenever I try to login (calling external API), I’m getting the segfault. Same goes for creating a new user, when calling the external API from my MVC backend.

Running the app locally, everything works as expected, and I can login fine, as well as creating a new user.

I have a try/catch around the enitre method, but I’m never hitting the catch. The segfault happens instead of the catch.

Technical details

@leecow is Debian 9 supported by 1.0?

No, Debian 9 is 2.0. https://github.com/dotnet/core/blob/master/os-lifecycle-policy.md.

I suppose that would explain some issues, but the application runs fine on the server. It’s only remote HTTP request that causes the segfault?

What version of curl and openssl do you have? This may be same as dotnet/runtime#23965 and dotnet/runtime#23796 You can try container with supported OS. That should get you around linkage problems.

@wfurt

OpenSSL version: OpenSSL 1.10f 25 May 2017

curl version: curl 7.52.1 (x86_64-pc-linux-gnu) libcurl/7.52.1 OpenSSL/1.0.2l zlib/1.2.8 libidn2/0.16 libpsl/0.17.0 (+libidn2/0.16) libssh2/1.7.0 nghttp2/1.18.1 librtmp/2.3

I don’t know what issues you are referring to (#24891 and dotnet/runtime#23796)?

I’m trying to convert my project to .NET core 2.0, and updating the installed version on my server. I will update my progress here once done. Thanks for the inputs.

@ChristianHaase commented on Sat Feb 24 2018

I updated the project to 2.0, but it’s still a problem. I’ll take a look at the links you provided @wfurt

@ChristianHaase commented on Sat Feb 24 2018

I looked at the installed version of libcurl, and this is what I could find:

Anything I can do here?

I’m going to move this to the corefx repo where it will be tracked better.
