Hi, I've reduced this to a very small testcase, downloadable here:
http://www.libavg.de/test_collada_dlopen.zip I'd appreciate it if others could try this out: $ ./build_collada_test.sh $ ./test_collada_static $ ./test_collada_dlopen $ diff collada_dlopen_converted.osg collada_static_converted.osg The test executables each use the same two lines to read a collada file and write it again, but the second one executes the code in the context of a dynamically-loaded .so. On Ubuntu 8.10 and 9.04, the second version is broken. On the mac, everything is ok.
