Did you rebuilt the shared library with the 2009q3-67 release as well?  There are known (and fixed) bugs caused by incompatibilities between RealView-built libraries Sourcery G++-built executables.

Make sure that the library and the executable are compiled with no stray exception-related options like -fno-unwind-tables.

Another common source of uncaught exceptions is a C function on stack; any C code that may have to pass through C++ exceptions need to be compiled with additional options.

If nothing else, you can try rebuilding both your application and your libraries with a more recent toolchain release, e.g., Sourcery CodeBench Lite 2011.03-41.

Hope this helps,
