The following patch fixes the test case.
However, if one comments the "STOP 'Success'" line, one sees that there is
another bug (double free). The problem is that _copy does not properly do a
deep copy.
Expected: A deep copy of both attractor%state and
attractor%integrand%quadrature.
Currently:
__copy_lorenz_module_Lorenz
{
*dst = *src;
dst->integrand = src->integrand;
__builtin_memcpy (dst->state.data, src->state.data, D.1953 * 4);
Thus, there is no deep copy of "attractor%integrand%quadrature"; thus, both
src->integrand->quadrature->_data and dst->integrand->quadrature->_data point
to the same memory, causing - for the example program - a segfault at the end
of the main program.
