FYI this has been solved by ABRT - Automated Bug-Reporting Tool
https://fedorahosted.org/abrt/
(it is distro-neutral despite its homepage)
Core file is there a subdirectory where the core file is just one of the many
associated files:
/var/spool/abrt/ccpp-*:
abrt_version analyzer architecture cmdline component coredump count
dso_list environ executable hostname kernel maps os_release package
pid pwd reason time uid username uuid var_log_messages
More info files are being continually added, such as /proc/PID/fd{,info}/
mapping at the crash dump time etc. You would need to add many more core file
notes to make the core files useful for later analysis.
