[Bug c++/39259] New: internal compiler error: in initialize_cfun, at tree-inline.c:1749

["patrakov at gmail dot com" <gcc-bugzilla@gcc.gnu.org>]

This meaningless testcase (reduced by delta from the real program), when
compiled with g++ 4.4 (but not 4.3), produces an ICE.

extern "C" int __mysetjmp () __attribute__ ((__returns_twice__));

class TContStatus {};

class TContEvent
{
public:
  inline void Execute () throw();
};

class TCont
{
public:
  TContStatus ReadD (void* buf, int deadline)
  {
    TContEvent event;
    event.Execute ();
    return TContStatus();
  }
  TContStatus ReadI (void *buf)
  {
    return ReadD (buf, 1);
  }
};

void TContEvent::Execute () throw ()
{
  __mysetjmp();
}

void Broken (TCont *mCont)
{
  mCont->ReadI(0);
  mCont->ReadI(0);
}
