In todays side story we witness the transmutation of virStorageSource
into a virObject.
Peter Krempa (5):
util: Introduce function for allocating virStorageSource
util: storage: Turn virStorageSource into a virObject
util: alloc: Introduce VIR_AUTOUNREF macro
util: Remove the AUTOPTR func for virStorageSource
util: Replace virStorageSourceFree with virObjectUnref

Is this right? @def is VIR_ALLOC'd and not virStorageSourceNew alloc'd.
Also anything that calls this would have the same problem I would think.
FWIW: This module is the one I ran afoul of the MinGW builds when trying
to use VIR_AUTOPTR. I see no change in here to use VIR_AUTOUNREF, so I
assume this was the way around it, albeit without the object alloc.

No. virStorageSource now must be allocated using virStorageSourceNew.
The first patch missed fixing this instance.
I'll post a patch soon.
