Wow, great start!

Yes - that is core of the trouble; as usually, the class is not
documented, so the purpose is not really visible:

http://opengrok.go-oo.org/xref/writer/sw/source/core/crsr/callnk.hxx
http://opengrok.go-oo.org/xref/writer/sw/source/core/crsr/callnk.cxx

like a kind of 'guard' that restores/updates stuff when the SwCallLink
instance is destructed.

Either way; I'd try to revert the callnk.cxx changes from commit
47472e8e70c1ae3dc55a5b00ef69eaa85f651a7f, it has something to do with
tables, and see if you still see the problem.  If not, then it might
limit the scope of your debugging to that commit only.

Hopefully I am not misleading you :-)

And Pascal - great work translating the comments there, thank you!
