* summary: Memory Leak in libsingular => [with patch, needs review,
needs more work] Memory Leak in libsingular
Comment:
The patch `libsingularLeak.patch` partially solves the problem.
I observed that when a coercion error occurs an intermediately generated
ideal `_I` is explicitly destroyed with `id_Delete(&_I,r)`. But when there
is no error and the result is returned, then `_I` is not deleted. But I
think it should.
With the patch, the above `Test(I)` still shows an increase of memory, but
a rather moderate increase. So, it seems to be a partial solution of the
problem, but more needs to be done.
