>          Issue Type: Bug
>          Components: C glib - Compiler
>    Affects Versions: 0.9.1
>         Environment: Fedora 20 64-bit on x86_64
>            Reporter: Simon South
>            Priority: Minor

> In the c_glib implementation, attempting to deserialize a map that uses a typedef'd type for its keys will usually result in a segmentation fault.
> This is because the code in the compiler that generates a variable declaration for a pointer to key values fails to first resolve the typedef to its underlying type. In most cases it will therefore generate incorrect code, effectively allocating a variable on the stack but later using it as though it were a pointer.
> The attached patch fixes this. (No test case is provided, but the integration test implementation I'm about to submit relies on this patch.)
