            Bug ID: 114854
           Summary: [14 Regression] ICE with default initializer of const
                    reference member at cp/cp-gimplify.cc:900
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED

  Target Milestone: ---

Compiling the following code results in an internal compiler error when usi=
ng
GCC 14 trunk (gcc-14-10094-g0c8e99e5c32). GCC 13.2 is fine with it.

class Vector {
  long m_size;
};
struct ProcessSpawnOptions {
  Vector const &file_actions {};
};

void spawn(ProcessSpawnOptions);
void test() { spawn({}); }


<source>: In function 'void test()':
<source>:9:20: internal compiler error: in cp_gimplify_expr, at
cp/cp-gimplify.cc:900
    9 | void test() { spawn({}); }
