It is difficult to say why the unit test fails. Would be possible to run it in
GDB and figure out why it segfaults?

The patch fixed weakrefs problems.
Compilation goes further and some undefined stuff in libreoffice is met:

OK, I think I found the bug. Weakrefs are considered to be external but they
need to be duplicated. Does the following fix the problem?

Ok, I got a self contained testcase for this and indeed, it is safe to remove
that assert. In fact it is yet another problem with weakrefs: we have weakrefs
that are referring

Hmm, not weakref but really weak alias of external function. This seems even
more weird.
What are the flags used to compile the .o file?

Hi,
I can not find any symbol

Hi,
you are right, the symbol is also missing in FieldCacheImpl.o.
Unlike FieldCacheImpl.o, propagg.o really contains symbol:

So the symbol is really external :

Hmm, the failing test is:

or add external symbol. */
