22.1.1. Debugging a crash dump with DDD

Examining a kernel crash dump with a graphical debugger like ddd is also possible. Add the option -k to the ddd command line you would use normally. For example:

  ddd -k /var/crash/kernel.0 /var/crash/vmcore.0
  
You should then be able to go about looking at the crash dump using DDD's graphical interface.
