Deleting key results in infinite loop.

[dicroce]

Deleting a particular key (5), then search's for it get stuck in infinite loop.

BPlusTree tree(3);
tree.insert(5);
tree.insert(3);
tree.insert(8);
tree.insert(69);
tree.insert(10);
tree.insert(12);
tree.insert(22);
tree.insert(72);
tree.insert(39);
tree.bpt_print();
assert(tree.search(5));
assert(tree.search(3));
assert(tree.search(8));
assert(tree.search(4) == false);

// Test delete
tree.remove(5);

assert(tree.search(5) == false);
printf("HERE 1\n");

assert(tree.search(3));
assert(tree.search(8));

In the function Removepar, the code in line 731

rightsibling->size = rightsibling->size + cursor->size+1

should be changed to

cursor->size = rightsibling->size + cursor->size+1
