libs/pool/test/test_simple_seg_storage.cpp produces bus error on 64-bit Solaris SPARC architecture

[Mike Liang <mtliang@…>]

main() in test_simple_seg_storage.cpp adds blocks with offsets of 0, 49 and 25. This results in non-word aligned access and a bus error on the Sparc Solaris architecture for the latter two when built and run in 64-bit mode. It looks like the offsets should have been 48 and 24 since the all three requested chunk sizes are 24.
