[GiNaC-list] memory leak when constructing expression from a string

[Alexei Sheplyakov]

Hello!

This silly program

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

int main(int argc, char** argv) {
	ex e;
	const symbol x("x"), y("y");
	const lst syms(x, y);
	static const char* str[] = { "x^2+2*x*y + cos(x)", "Li2(x/y) + log(y/x)" };
	unsigned N=0;
	try {
		for (; ; N++) {
			e = ex(str[N & 1], syms);
		}
	} catch (...) {
		cerr << "N = " << N << endl;
		return 1;
	}
	return 0;
}

exhausts all the available memory. I don't think this is correct
behaviour. Any suggestions how to fix this?

Best regards,
	Alexei
