Hi, If I try to print a non-existing member of task_struct with foreach, I get expected error messages: crash> foreach task -R invalid PID: 0 TASK: 806d9d30 CPU: 0 COMMAND: "swapper/0" task: invalid: not a task_struct or thread_info member PID: 0 TASK: 8fce2808 CPU: 1 COMMAND: "swapper/1" task: invalid: not a task_struct or thread_info member PID: 1 TASK: 8fc9c768 CPU: 0 COMMAND: "systemd" task: invalid: not a task_struct or thread_info member But, if I try to do this with a non-existing submember of an existing member, I get 'recursive temporary file usage': crash> foreach task -R se.invalid PID: 0 TASK: 806d9d30 CPU: 0 COMMAND: "swapper/0" task: invalid data structure member reference: se.invalid task: recursive temporary file usage task: recursive temporary file usage task: recursive temporary file usage task: recursive temporary file usage This is with the the latest crash from git. I think this started from the patches which introduced the deep-printing of structures. I haven't investigated further yet, though.
