The answers given here cover pretty well most scenarios for which core dump is not created. However, in my instance, none of these applied. I'm posting this answer as an addition to the other answers.

If your core file is not being created for whatever reason, I recommend looking at the /var/log/messages. There might be a hint in there to why the core file is not created. In my case there was a line stating the root cause:

Executable '/path/to/executable' doesn't belong to any package

To work around this issue edit /etc/abrt/abrt-action-save-package-data.conf and change ProcessUnpackaged from 'no' to 'yes'.

ProcessUnpackaged = yes

This setting specifies whether to create core for binaries not installed with package manager.
