I am unable to reproduce this problem, and code inspection does not
reveal any place where source would be sorted or otherwise rearranged.
Can you give me instructions how to reproduce this? If you point me
at some SVN branches, that's fine, but please make sure this reproduces
in unmodified state of some revision -- and tell me that revision.
