https://sourceware.org/bugzilla/show_bug.cgi?id=34482

            Bug ID: 34482
           Summary: Ptrace error during attach is not reported
           Product: gdb
           Version: 17.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: dap
          Assignee: unassigned at sourceware dot org
          Reporter: dmitry.neverov at jetbrains dot com
  Target Milestone: ---

To reproduce on Ubuntu:
- run echo 1 | sudo tee /proc/sys/kernel/yama/ptrace_scope
- attach to a running process with gdb

Gdb/mi reports the ptrace error:

  >24-target-attach 29838
  <24^error,msg="ptrace: Operation not permitted."
  <(gdb)

Gdb/dap logs the error but reports success:

  READ: <<<{"type": "request", "seq": 2, "command": "attach", "arguments":
{"pid": 30919}}>>>
  ...
  READ: <<<{"type": "request", "seq": 4, "command": "configurationDone",
"arguments": {}}>>>
  WROTE: <<<{"request_seq": 4, "type": "response", "command":
"configurationDone", "success": true}>>>
  +++ attach 30919
  Traceback (most recent call last):
    File
"/home/nd/.local/share/JetBrains/Toolbox/apps/clion/bin/gdb/linux/x64/share/gdb/python/gdb/dap/startup.py",
line 212, in exec_and_log
      output = gdb.execute(cmd, from_tty=True, to_string=True)
               ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

  gdb.error: ptrace: Operation not permitted.
  WROTE: <<<{"request_seq": 2, "type": "response", "command": "attach",
"success": true}>>>

After that gdb/dap doesn't repond to other commands, like pause.
