[Bug c++/24686] New: ICE when building a variation of NMSTL

[christian dot convey at gmail dot com]

We have a customized version of the NMSTL library, and get an ICE when we build
it. (Sorry, I couldn't find directions on how to fill out Host triplet, Target
triplet, and Build triplet.)

I'm using Ubuntu Linux 5.10.

As far as I can see this is valid code (the machine which was doing the
reduction crashed or something because I cannot connect to it).

Confirmed, reduced testcase:
struct string {
   struct _Alloc_hider {
   ~_Alloc_hider();
  };
    mutable _Alloc_hider _M_dataplus;
  };
  template<class T> string to_string(const T& t);
  struct debug_msg {
    debug_msg(int);
    template<class T>  debug_msg& operator << (const T& t);
  };
  struct debug {
    static debug& get() {
}
    bool operator ^ (const debug_msg& msg);
  };
  int f();
  int i;
  void set_handler(int fd) {
    (i >= 1)&& debug::get() ^ debug_msg(({
 static int l = f();
 l;
}
 ))  << to_string(1);
  }

Further reduced:

bool h(int, const A&);
int f();
int i;
void g()
{
  i && h (({ static int l = f(); l; }),
