>Description:
The compiler segfaults when compiling the following file
with "-g -finline-functions". Note that the __complex__
construct is used in <complex> on my platform.

#if 0
namespace std {
  template<typename _Tp>
  struct complex;
  
  template<>
  struct complex<double>
  {
    typedef __complex__ double _ComplexT;
    _ComplexT _M_value;
  };
}
#else
# include <complex>
#endif

template <typename T>
struct X
{
  X (X<T> const &, T);
};

template <typename T>
X<T>::X (X<T> const &, T s)
{
}

template class X<std::complex<double> >;
>How-To-Repeat:
g++ -g -finline-function f.cxx
>Fix:
Don't know.
Hint: the problem goes away if -g or -finline-functions
is omitted or if the parameter "s" to X<T>::X() is omitted.
