Sorry, I think the correct message is "Aborted". I've run it through
strace and in the very end, it prints this:

(...)

It closes stdout, then detects an unmet assertion that it wants to print
to stdout but that fails. Then the ABRT signal is unblocked (whatever
that means) and finally mono seems to abort itself.

Is that normal? It only happens with some programmes and only if they do
certain things.

This is what an un-aborted end looks like:

(...)

> unlink("/dev/shm/mono.19532")           = 0
> exit_group(0)                           = ?

(no close(0/1/2) here)
