Earlier this evening I installed .NET core preview 2 on Debian Sid, and tried to create a new project via the dotnet new command, only to get a segmention fault error message:

matt@IDSiG:~/git/testproject$ dotnet new console
Segmentation fault

In this instance, the segmentation fault on creation of a new project was is due to .NET Core telemetry being incompatible with version 1.1 of OpenSSL.
