Hello everyone,
I use VS C++ 2008 with Intel Compiler. The compiler is not able to pass through the Eigen library when builds a x64 plattform application.

Here is the output:

1>Compiling with Intel(R) C++ 10.1.021 [Intel(R) 64]... (Intel C++ Environment)
1>ComponentRastrigin.cpp

The problem with access to the components of the class "__m128" has already been reported to the Intel (e.g. http://software.intel.com/en-us/forums/ ... hp?t=67800).

Of course, the problem disappears when I use the MSC Compiler.

Any advices how to manage with the Intel Compiler problems by apropriate configuration or modification of the Eigen Library as well as by configuration of VS project preferences would be appreciated.
Thanks,
Krzysztof

should be fixed in both branches.
