I'm in the process of porting a C++ application from a sun3 to a sun4 and
I've run into a problem with stdargs.  I wrote the following little test
program to show the problem.  I'm using C++ 2.0.  We're running Sun OS 4.0.


#include <stdarg.h>

void output( int, ... );

main()
{
	output( 1, 2, 3, 0 );
}

void output( int j, ... )
{
	va_list	ap;
	va_start( ap, j );

	int	i;

	printf( "%d\n", j );

	while ( ( i = va_arg( ap, int ) ) != 0 )
	{
		printf( "%d\n", i );
	}

	va_end( ap );
}

On the sun3 the output is as expected:

1
2
3


However, on the sun4 we get:

1
32768
8192


The stdarg.h files for sun3 and sun4 are identical.  Does anyone know the fix
for this or can anyone at least confirm that this problem exists on their
sun4s?  Thanks much.
