Crash with slice2py When Compiling cpp/src/IceGrid/Internal.ice

[InsertCreativityHere]

Normally this file is only compiled with slice2cpp, so we never noticed.
But it's completely broken with a debug build of slice2py on Windows (and MacOS, confirmed by externl).

After cutting out parts of the file and seeing what still triggers the abort, the issue is caused by malformed @param tags:

module IceGrid
{
    interface Adapter
    {
        /// @param The direct proxy.
        void setDirectProxy(Object* proxy);
    }
}

It seems we didn't write @param proxy like we should of. But, this also shouldn't cause the compiler to crash either.

This is also broken on 3.7.
