Detailed Description

*' dumps when a BmnRoot process is terminated by a fatal signal. The guard is installed automatically when the library is loaded, so no changes in the macros are required. It works regardless of the 'ulimit -c' value and of the /proc/sys/kernel/core_pattern setting, which makes it usable on the user machines as well as on the cluster nodes.
