I think this has been answered before: it doesn't work when the
functions are in libraries. It only works when the respective
functions are in explicitely linked object files.
Jean-Christophe is planning to switch to linking objects like the
Linux kernel does, but this is a medium/long term task.
For now, check if you can separately link the respective object files.
See the ML archive for the previous discussion.
Best regards,

It seems intuitively obvious to me, which means that it might be
wrong. -- Chris Torek
