In PyView.cpp, PyView_repeat(), the statement seems leaking
tmp = new PyView(tmp->Concat(*o), 0, o->computeState(RWVIEWER)); //!! a huge
stack of views?
An alternative is
PyView *tmp1 = new PyView(tmp->Concat(*o), 0, o->computeState(RWVIEWER)); //!!
a huge stack of views?
delete tmp;
tmp = tmp1;

Thanks, change applied to CVS.
