LHS and RHS of the assignment-operator should not be the same.
(The code perhaps should be 'dup->cone = tab->cone;'.)

llvm-project/polly/lib/External/isl/isl_tab.c:line 295

   295          tab->cone = tab->cone;
   296          dup->bottom.type = isl_tab_undo_bottom;
   297          dup->bottom.next = NULL;
   298          dup->top = &dup->bottom;

   300          dup->n_zero = tab->n_zero;
   301          dup->n_unbounded = tab->n_unbounded;
   302          dup->basis = isl_mat_dup(tab->basis);
   303  
   304          return dup;
