[Bug c++/34972] New: ICE in write_type, at cp/mangle.c:1648

[marcin-konarski at o2 dot pl]

Presented test case produces following output:

g++ ice.cxx
ice.cxx: In member function '__typeof__ (ice<function_t>::tp(tType()))
ice<function_t>::foo(const tType&) const [with tType = int, function_t = bool
(*)(long int)]':
ice.cxx:9: internal compiler error: in write_type, at cp/mangle.c:1648

The test case:
ice.cxx:

template<typename function_t>
struct ice
  {
  function_t const& CALLER;
  static function_t tp;
  ice( function_t const& func ) : CALLER( func ) { }
  template<typename tType>
  typeof( tp( tType() ) ) foo( tType const& value ) const
    { return ( CALLER( value ) ); }
  };

bool iceh( int long a )
  {
  return ( a > 1 );
  }

int main( int, char** )
  {
  return ( ice<typeof(&iceh)>( &iceh ).foo( 3 ) ? 7 : 13 ) ;
  }
