Yes, this could be a compiler/ABI mismatch between the compiler that
you use to build the example and that was used to build the libodb*
packages (I assume you are using system-installed ones).

If you want to try to eliminate this possibility, I would suggest
building the 2.5 pre-release from source as described here:

https://codesynthesis.com/products/odb/doc/install-build2.xhtml

Otherwise (or if you have the same issues with 2.5), you will
need to build the test with debug information (-g) and look
around in the debugger (e.g., stack trace, etc) for what might
be causing this.
