Short description of error
When skinned meshes are exported with FBX 7.4 binary the position of vertices does not export correctly.
As a result meshes are deformed (visible but not extreme in most cases) after export.
Note that external tools/software may be required to compare the meshes as the bug may be invisible upon re-import to blender.
A good way to see the differences is to use the mesh wireframe in iso view in blender versus unity for example.

Exact steps for others to reproduce the error
- Load the attached blend file.
- Export to FBX using 7.4 binary
- Compare the position of vertices before and after export.
