[Daniel van Vugt (vanvugt)]

Lack of a core file/backtrace appears to be Mir's fault:
examples/server_example.cpp: char const command_fmt[] = "/usr/share/apport/recoverable_problem --pid %d";

No application should be doing that. We have error reporting built into the OS, which is more reliable.

Try this:
$ ulimit -c unlimited
$ mir_demo_server --on-fatal-error-abort

Do you get a core file?

[Daniel van Vugt (vanvugt)]

Alternatively, try installing 'apport' to get that binary that you are missing.

[Daniel van Vugt (vanvugt)]

And please also try 'mir_proving_server'.
