Much reduced test case:

struct typeBase
{
  constexpr typeBase() : Lvalue() {}
  int Lvalue;
};

struct type : private typeBase
{
  bool value;
  type(bool v = 0) { value = v; }
  consteval type(int i) { value = i; }
  const bool operator*() const { return value; }
};

auto operator > (const type&a, const type&b) { return *a > *b; }

int main() {
  type T;
  if (T > type(100)) { }
}

And the assertion that fails is:

clang++: /home/tbaeder/code/llvm-project/llvm/lib/IR/Instructions.cpp:1491: void llvm::StoreInst::AssertOK(): Assertion `cast<PointerType>(getOperand(1)->getType()) ->isOpaqueOrPointeeTypeMatches(getOperand(0)->getType()) && "Ptr must be a pointer to Val type!"' failed.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.
Stack dump:
0.	Program arguments: bin/clang++ ./test.cpp -std=c++2a -c
1.	<eof> parser at end of file
2.	./test.cpp:23:5: LLVM IR generation of declaration 'main'
3.	./test.cpp:23:5: Generating code for declaration 'main'
(etc.)

Removing the consteval from the type(int i) constructor makes it work.

I think this may be related to or a duplicate of #51764.

The reduced test case no longer crashes on trunk, but the original test case does still crash when emitting codegen.
