Version: 1
[Error - 9:38:08 AM] The Clang Language Server server crashed 5 times in the last 3 minutes. The server will not be restarted. See the output for more information.
```
And the version:
```
> clangd --version 9:45
clangd version 18.1.7
Features: linux
Platform: x86_64-unknown-linux-gnu; target=x86_64-1a-linux-gnu
```
And here is a snippet of the file near line 238 (template member function definition of a template class):
```
template <class... Args>
template <class BaseHandle_t, class T, class Functor>
SI_REQUIRES(std::invocable<Functor const, std::shared_ptr<T>, Args...>)
NotifierSubscriptionPtr Notifier<Args...>::Impl::Subscribe(
Ptr_t const& ioSelf, std::shared_ptr<T> const& iObj, Functor iFunc)
{ // line 238
```
with `#define SI_REQUIRES(...) requires __VA_ARGS__`
Thank you!
