Reduced by me and C-Reduce:

struct BasicPersistent {
  BasicPersistent(const char * = __builtin_FUNCTION());
};

BasicPersistent& declval();

template <typename... _Args>
auto construct_at(_Args &&...) -> decltype(new BasicPersistent()) {}

struct CFXJSE_Engine {
  void AddObjectToUpArray();
};

void CFXJSE_Engine::AddObjectToUpArray() {
  construct_at();
}

I got two more crashes out of this reproducer. I'll reduce them as well, and file separate issues for them.

I am facing the same issue. Is there any way to fix this?

It looks like this was a clang-18 regression: https://godbolt.org/z/vfo1rExah

But the error message in OP shows llvm / clang 19 and i am also using version 19.

Yes but the crash started happening in clang-18.

i also face the same issue when compiling llvm (currently version 20.0.0_pre20240830) with both llvm 20.0.0_pre20240822 and 19.1.0_rc3. llvm 18.1.8 does not crash though.

@fordfrog For some reason Gentoo has enabled debug on LLVM / Clang by default. I've got around this error by disabling it.

oh thanks, disabling debug made me evade this issue too.

@Endilll @shafik Looks like this no longer crashes on trunk (or 19.1); I think we can close this now?
