Subject: [PATCH] qom: fix refcount of non-heap-allocated objects
|
|
MIME-Version: 1.0

Content-Type: text/plain; charset=UTF-8

|
|
The reference count for embedded objects is always one too low, because
|
|
object_initialize_with_type returns with zero references to the object.
|
|
This causes premature finalization of the object (or an assertion failure)
|
|
after calling object_ref to add an extra reference and object_unref to
|
|
remove it.
|
|
|
|
The fix is to move the initial object_ref call from object_new_with_type
|
|
to object_initialize_with_type.
