           Summary: ICE: in tsubst_expr, at cp/pt.cc:22244
           Product: gcc
           Version: 14.2.1
            Status: UNCONFIRMED
          Keywords: ice-on-invalid-code
          Severity: normal
          Priority: P3

  Target Milestone: ---

Hello!

I encountered an ICE on GCC when I was trying to run the official test suite on
the latest version of the compiler and forgot to type a corresponding '}'
specifier by accident. I have tried to simplify the code:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

#define SA(X) static_assert(X, #X)
struct S2 {
  struct V {    
};

template<typename T>
struct S5 {
  void f1() noexcept(noexcept(i)) { }
  int i;
};

S5<int> s5;
SA(noexcept(s5.f1()));

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Please check https://godbolt.org/z/GEYde8dod.

Compiler Output:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

<source>: In instantiation of 'void S2::S5<T>::f1() [with T = int]':
