That creates a cross-heap reference loop and it's very bad news for the GC. > As a temporary workaround I removed the "value state_value" field from the > ocaml_data struct, replacing it with a reference counter: Maybe you could try something similar, with a weak hash table to recover the OCaml value corresponding to a given lua_State, thus eliminating the need for a reference counter. Use the address of the lua_State for hashing and for comparison. Drawback: the weak hash table has to be global. -- Damien _______________________________________________ Caml-list mailing list.
