Case 1: Adding Poses to Pose Library

With the given test file
bone_cow-poselib_usercount_bug.blend347 KBDownload
Add a Pose Library (via properties editor)
Add a new pose to pose library (via properties editor)
Note that usercount of active action (see Dopesheet) increases
Repeat... usercount increases every time.

Tested with 0636acc59ab + --enable-copy-on-write

Actually the usercount gets incremented in pose mode by doing anything action there ( move, scale, selection, rotate ), and note that COW is now default. If you play a bit with the file, just select some bones, rotate, scale, .... and do some undo in the middle, Blender will crash and sometimes not able to open the file anymore(crash on start).

Open the file and look at the usercount ->
