            Bug ID: 18717
           Summary: gdb misbehaves if non-leader thread exits process
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gdb
          Assignee: unassigned at sourceware dot org
          Reporter: palves at redhat dot com
  Target Milestone: ---

This affects both the native backend and gdbserver.

If a non-leader thread exits the process while all other threads are
ptrace-stopped, native gdb internal-errors.

I'm adding a test to the testsuite that catches this:

/home/pedro/gdb/mygit/build/../src/gdb/linux-nat.c:3198: internal-error:
linux_nat_filter_event: Assertion `lp->resumed' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)
FAIL: gdb.threads/non-leader-exit-process.exp: program exits normally (GDB
internal error)
