Using the native compilation branch, Create tmp.cpp with this:

```
// In state_machine
private: auto
state_machine::stop_bbbbbbb(states::recording &&s,
aaaaaa::bbbbbbb_stopped_reason reason)
-> fsm::state_machine<
aaaaaa::bbbbbbb::state_machine,
std::variant<aaaaa::bbbb::cccccc::ddddddd::eeeeee::aaaaaa_connected,
aaaaa::bbbb::cccccc::ddddddd::eeeeee::aaaaaa_disconnected,
aaaaa::bbbb::cccccc::ddddddd::eeeeee::aaaaaa_state,
aaaaa::bbbb::cccccc::ddddddd::eeeeee::aaaaaa_info,
aaaaa::bbbb::cccccc::ddddddd::eeeeee::aaaaaa_battery,
aaaaa::bbbb::cccccc::ddddddd::eeeeee::account_error,
aaaaa::bbbb::cccccc::ddddddd::eeeeee::account_valid>,
std::variant<aaaaa::bbbb::aaaaaa::bbbbbbb::states::init>>::state
```

Open using `emacs -Q tmp.cpp` and emacs freezes.

I managed to get some backtrace using `kill -USR2`:

* #f(compiled-function () #<bytecode 0xb89cd227791443a>)()
font-lock-default-fontify-region(35 597 nil)
c-font-lock-fontify-region(48 548 nil)
font-lock-fontify-region(48 548)
#f(compiled-function (fun) #<bytecode 0x1f23231d0aa2fbbe>)(font-lock-fontify-region)
run-hook-wrapped(#f(compiled-function (fun) #<bytecode 0x1f23231d0aa2fbbe>) font-lock-fontify-region)
jit-lock--run-functions(48 548)
jit-lock-fontify-now(48 548)
jit-lock-function(48)
redisplay_internal\ \(C\ function\)()

but at that point emacs is nearly unusable.
