In the meantime I tested with a gcc 4.0.4 built from the release sources. With
this gcc version the executable builds fine without errors and runs as expected.
The other parts of my environment didn't change, so this looks like a problem of
gcc version > 4.0.4
I attached my current example also containing the output of failure build with
"gcc/gcj -v" (4.1.2) and "nm -C" of the shared lib.
