Description

We are encountering random crashes with the following call stack

EmbeddedBrowserWebView.dll!mojo::core::ipcz_driver::anonymous namespace'::Close() EmbeddedBrowserWebView.dll!ipcz::DriverMemoryMapping::~DriverMemoryMapping(void) EmbeddedBrowserWebView.dll!absl::container_internal::raw_hash_set<absl::container_internal::FlatHashMapPolicy<ipcz::StrongAlias<ipcz::BufferIdTag,unsigned long long>,ipcz::DriverMemoryMapping>,absl::hash_internal::Hash<ipcz::StrongAlias<ipcz::BufferIdTag,unsigned long long> >,std::__Cr::equal_to<ipcz::StrongAlias<ipcz::BufferIdTag,unsigned long long> >,std::__Cr::allocator<std::__Cr::pair<const ipcz::StrongAlias<ipcz::BufferIdTag,unsigned long long>,ipcz::DriverMemoryMapping> > >::destroy_slots() EmbeddedBrowserWebView.dll!ipcz::BufferPool::~BufferPool(void) EmbeddedBrowserWebView.dll!ipcz::NodeLinkMemory::~NodeLinkMemory(void) EmbeddedBrowserWebView.dll!ipcz::RefCounted<class ipcz::NodeLinkMemory>::ReleaseRef(void) EmbeddedBrowserWebView.dll!ipcz::NodeLink::~NodeLink() EmbeddedBrowserWebView.dll!ipcz::NodeLink::scalar deleting destructor'(unsigned int) EmbeddedBrowserWebView.dll!ipcz::anonymous namespace'::NotifyTransport() EmbeddedBrowserWebView.dll!mojo::core::ipcz_driver::Transport::OnChannelDestroyed(void) EmbeddedBrowserWebView.dll!mojo::core::Channel::~Channel(void) EmbeddedBrowserWebView.dll!??_GChannelWin@?A0x743F16E8@core@mojo@@EEAAPEAXI@Z.c906ffe60f7ae0780f7a7cc206ef4576() EmbeddedBrowserWebView.dll!base::internal::BindState<void (mojo::core::(anonymous namespace)::ChannelWin::*)(),scoped_refptr<mojo::core::(anonymous namespace)::ChannelWin> >::Destroy() EmbeddedBrowserWebView.dll!base::TaskAnnotator::RunTaskImpl(struct base::PendingTask &) EmbeddedBrowserWebView.dll!base::sequence_manager::internal::ThreadControllerWithMessagePumpImpl::DoWorkImpl() EmbeddedBrowserWebView.dll!base::sequence_manager::internal::ThreadControllerWithMessagePumpImpl::DoWork(void) EmbeddedBrowserWebView.dll!base::MessagePumpForIO::DoRunLoop(void) EmbeddedBrowserWebView.dll!base::MessagePumpWin::Run(class base::MessagePump::Delegate *) EmbeddedBrowserWebView.dll!base::sequence_manager::internal::ThreadControllerWithMessagePumpImpl::Run(bool,class base::TimeDelta) EmbeddedBrowserWebView.dll!base::RunLoop::Run(class base::Location const &) EmbeddedBrowserWebView.dll!base::Thread::Run(class base::RunLoop *) EmbeddedBrowserWebView.dll!base::Thread::ThreadMain(void) EmbeddedBrowserWebView.dll!base::anonymous namespace'::ThreadFunc() kernel32.dll!BaseThreadInitThunk() ntdll.dll!RtlUserThreadStart()

Up to this point, I've been unable to reproduce it, and it has started crashing recently (Only a few crashes observed out of thousands of tests). It seems unrelated to any changes in our codebase, we are currently using version 118.0.2088.57.

Steps to Reproduce

1. So far, I haven't identified any, but I will update the issue if I discover any.

Let me know if you need additional information.
