Yes, modulo minor whitespace damage :)

I've found yet another bug (seems to be fixed in HEAD):

#include <iostream>
#include <stdexcept>
#include <ginac/ginac.h>
using namespace std;
using namespace GiNaC;

int main(int argc, char** argv)
{
	idx a(symbol("a"), 8), b(symbol("b"), 8), c(symbol("c"), 8),
			d(symbol("d"), 8), e(symbol("e"), 8), f(symbol("f"), 8);
	
	ex H1 = color_f(a, c, e)*color_f(b, d, e)
		   	+	color_f(a, d, e)*color_f(b, c, e);

	ex test = (H1*H1).expand(expand_options::expand_indexed);
	cout << test << endl;
  // 2*f.e.b.d*f.e.b.c*f.e.a.c*f.e.a.d+f.symbol8.b.c*f.symbol8.a.d*f.e.b.c*f.e.a.d+f.symbol7.b.d*f.symbol7.a.c*f.e.b.d*f.e.a.c
	// inconsistent indices!

	cout << test.simplify_indexed() << endl;
	// prints 288, should be 216

	return 0;
}

I wonder if it is possible to backport the fix...


Best regards,
 Alexei
