You missed that my testcase was the readelf output, not the runtime 
behaviour.  I didn't bother to transform it into a runtime 
testcase, the problem is obvious from readelf.  (You'd need dlsym to make 
this into a runtime testcase, because the whole point of the excercise is 
that app itself doesn't contain any explicit references to these symbols 
but still must contain definition of them)


Ciao,
Michael.
