How to get the PyBindGen PyObject for a given C++ pointer?

Given the PyObject created by PyBindGen, it's easy to get the pointer to the wrapped C++ object, just use the obj member in the struct:

typedef struct {
    PyObject_HEAD
    MyWrappedClass *obj;
    PyObject *inst_dict;
    PyBindGenWrapperFlags flags:8;
} PyMyWrappedClass;

However, let's say I have just MyWrappedClass*, and want to get the PyObject (if any, it might not exist) that wraps it. Is there any way to do this without maintaining my own dictionary of backpointers?

I would have added this as a comment if I had enough reputation as I'm not familiar with PyBindGen, but unless inst_dict is a dictionary of backpointers (as the name might suggest) I think you're out of luck (Unless you want to trawl through the Python heap to see if there are any instances of your class there).
