Hi Wolfgang,
I guess you have the problem that your compiled program is smaller
then the root exe hence your MapFile is allocated at too low
address space for root.
Please consult the following URL how to use SetMapAddress in
your program:

root.cern.ch/root/html/TMapFile.html#TMapFile:SetMapAddress

Cheers,
Otto
