> The attached patch to the compiler improves memory management in generated code relating to the deserialization of maps (implemented using hash tables in c_glib). It makes three changes:
> 1. Newly created hash tables are constructed with references to the correct hashing, comparison and deallocation functions, as determined by the types they hold.
> 2. Base types allocated on the heap will be automatically deallocated with the {{g_free}} function (instead of not being deallocated at all!).
> 3. The direct-comparison function is now explicitly specified for enumerated types, which are (somewhat dubiously) always stored _within_ a pointer value instead of on the heap.
> (No test case for these changes either, mostly as I'm unsure how I'd write one. Again the integration test serves as a pretty rigorous test of this code, though it completes with or without this patch applied.)
