bug in egcs 1.0.2 (SunOS 4)

[Tomislav Goles <tom at ait-tech dot com>]

The following code triggers internal compiler error with egcs 1.0.2
on sunos 4 ('uname -a' returns 'SunOS ga010085 4.1.4 1 sun4m').
The exact same code compiles fine on hpux 10.01 (with same egcs 1.0.2).

#include <cstdarg>
template< class T > class A {};
template< class T > void foo( int c, const A< T > * p, ... )
{
  typedef const A< T > * Ty;
  va_list Ap;
  va_start( Ap, p );
  for( int i = 1; i < c; i ++ )
    Ty b = static_cast< Ty >( va_arg( Ap, Ty ) ); // line 9
}
