dotnet application crash with segfault libcoreclr.so (debian 8, centos 7)

[OleksiiChuiko]

I have dotnet core 2 application that works fine on Windows. But when I start it on Linux debian 8 or centos 7 the application crashes after a while and see the following messages in the logs:

Is it problem with .net system? How to fix this?

Want to note that the dotnet application is started as a service using systemctl.

[wfurt]

can you come up with some simplified repro app?
Does it crash when you start it from shell?
Did you get core file after the crash?

When I attached with gdb I get the following dump:

Sorry, problem was with service settings - Type must be simple and no restart
