Your code does not compile.

1. proto_slapml is not defined. You pass the return value of 
proto_register_protocol to this variable.

2. proto_testdissect is -1 and can cause this exception, when you pass this 
to proto_tree_add_item.

3. The function proto_tree_add_item does not expect a return value from 
proto_register_protocol but a hf index created by 
proto_register_field_array.
see prototype:
proto_tree *proto_tree_add_item(proto_tree *tree, int hfindex, tvbuff_t 
*tvb,
    gint start, gint length, gboolean little_endian);
