At a guess, the reference is from your C++ shared library. You can verify that by using "readelf -r" and "readelf -s" on the shared library and looking for atexit. If you find it there as an undefined symbol, then what is the command that you use to build your shared library? > I tried with > "configure --disable-shared" and it worked for us.
