[Lldb-commits] [PATCH] D86388: Fix use-after-free in ThreadPlan, and add test.

[Nicholas Allegra via Phabricator via lldb-commits]

comex added a comment.

The sequence I found is:

- `WillResume`
- `DoResume` sends `eBroadcastBitAsyncContinue` to `ProcessGDBRemote::AsyncThread`
- `AsyncThread` calls `process->SetPrivateState(eStateRunning);`
- …which sends `eBroadcastBitStateChanged` back to the main thread, handled by `Process::HandlePrivateEvent`
- …which ends up in this stack, when it tries to figure out whether to report the state change to the user:
  - `Process::HandlePrivateEvent` ->
  - `Process::ShouldBroadcastEvent` ->
  - `ThreadList::ShouldReportRun` ->
  - `Thread::ShouldReportRun` ->
  - `ThreadPlan::ShouldReportRun` ->
  - `ThreadPlan::GetPreviousPlan` ->
  - `ThreadPlan::GetThread`
