[redland-dev] referencing models from queries

[Maxence Guesdon]

Hello,

For my ocaml-rdf bindings, I encounter the following problem:

I create a model, then a query and execute the query. If the model was
freed (because it was reclaimed by the garbage collector which then calls
the librdf_free_model function), it seems that the model reference in the query
becomes invalid (I get a segfault).

The attached patch (apparently) solves the problem, but is it the right way
to go ?
What it does: increment reference count to model when executing the query,
free the model when terminating the query.

Regards,
