Hi Jan,
sorry for my delay in replying. Given that your answer suggests it might 
not be as trivial as I thought, I decided to simply re-compile the 
crashing xen (including symbols and the debug option) and attach the 
complete build log which to me looks as if it includes all flags used 
for every object built. The file is long, thus compressed, but I am sure 
your are able to immeditately spot what to look for.

Thanks Atom2
