             Bug #: 13217
           Summary: thread apply all detach throws a SEGFAULT
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: threads
        AssignedTo: unassigned@sourceware.org
        ReportedBy: kevin.pouget@gmail.com
    Classification: Unclassified


thread apply all detach throws a SEGFAULT, because

thread.c:thread_apply_all_command
  for (tp = thread_list; tp; tp = tp->next)

is not robust against thread_list modification during the loop.


The reason behind this strange-looking command is when you have multiple
(single-threaded) inferiors and you want to detach all of them, there is no
`inferior apply all detach`
