Hi,
Yesterday with Armin we hit a very very strange issue with MSVC 2008
(vectorization enabled).
The test_sizeof was failing for him, on the first subtest (Matrix<float,1,1>).
It turned out that he had sizeof(Matrix<float,1,1>)=8, sizeof(float)=4.
What can possibly have happened?
I've been thinking about possible bugs in the logic of
ei_matrix_storage but that wouldn't be compiler-dependent and of
course I don't have this issue here with gcc...
Cheers,
Benoit
