Message:

Aborts now create core dumps which are printed by the test harness.

  • printing is done with gdb, print-core.gdb is the list of commands that will print
  • since all core dumps are assumed to be call 'core' this doesn't handle fancy core patterns and has race conditions if multiple program core dump.
