I've tried the example on MacOS 10.7.4, with the default clang 3.1 from
Apple and the two days ago released Eigen 3.1 and it works fine.

AFAIK the default compiler for 10.6.8 is llvm-gcc-4.2 which is rather
ancient, but should be fine. Can you be a little bit more specific about
what happens, e.g. compile in debug and add a stack trace here so we
have an idea in which direction to look?
