There is another core file under
/cores_data/pool-1/data2/72998388/core-lib-data
for pid 2553, with simliar kind of crash but different
stack trace.

Both crashed with Bus Err with ENOMEM, but there seems to be more than
enough free space left, and customer/on-site SE do not believe this
is a case of memory resource.
